Features include:

* :Gblame for interactive vertical split with git blame output.
* :Ggrep to search the work tree (or any arbitrary commit) with git grep,
  skipping over that which is not tracked in the repository.
* :Glog loads all previous revisions of a file into the quickfix list so
  you can iterate over them and watch the file evolve.
* :Gbrowse to open the current file on GitHub, with optional line range
  (try it in visual mode).

+
+INTRODUCTION *fugitive*
+
+Whenever you edit a file from a Git repository, a set of commands is defined
+that serve as a gateway to Git.
+
+COMMANDS *fugitive-commands*
+
+These commands are local to the buffers in which they work (generally, buffers
+that are part of Git repositories).
+
+ *fugitive-:Git*
+:Git [args] Run an arbitrary git command. Similar to :!git [args]
+ but chdir to the repository tree first.
+
+ *fugitive-:Git!*
+:Git! [args] Like |:Git|, but capture the output into a temp file,
+ and edit that temp file.
+
+ *fugitive-:Gcd*
+:Gcd [directory] |:cd| relative to the repository.
+
+ *fugitive-:Glcd*
+:Glcd [directory] |:lcd| relative to the repository.
+
+ *fugitive-:Gstatus*
+:Gstatus Bring up the output of git-status in the preview
+ window. The following maps, which work on the cursor
+ line file where sensible, are provided:
+
+ <C-N> next file
+ <C-P> previous file
+ <CR> |:Gedit|
+ - |:Git| add
+ - |:Git| reset (staged files)
+ cA |:Gcommit| --amend --reuse-message=HEAD
+ ca |:Gcommit| --amend
+ cc |:Gcommit|
+ cva |:Gcommit| --amend --verbose
+ cvc |:Gcommit| --verbose
+ D |:Gdiff|
+ ds |:Gsdiff|
+ dp |:Git!| diff (p for patch; use :Gw to apply)
+ dp |:Git| add --intent-to-add (untracked files)
+ dv |:Gvdiff|
+ O |:Gtabedit|
+ o |:Gsplit|
+ p |:Git| add --patch
+ p |:Git| reset --patch (staged files)
+ q close status
+ R reload status
+ S |:Gvsplit|
+
+ *fugitive-:Gcommit*
+:Gcommit [args] A wrapper around git-commit. If there is nothing
+ to commit, |:Gstatus| is called instead. Unless the
+ arguments given would skip the invocation of an editor
+ (e.g., -m), a split window will be used to obtain a
+ commit message. Write and close that window (:wq or
+ |:Gwrite|) to finish the commit. Unlike when running
+ the actual git-commit command, it is possible (but
+ unadvisable) to muck with the index with commands like
+ git-add and git-reset while a commit message is
+ pending.
+
+ *fugitive-:Ggrep*
+:Ggrep [args] |:grep| with git-grep as 'grepprg'.
+
+ *fugitive-:Glgrep*
+:Glgrep [args] |:lgrep| with git-grep as 'grepprg'.
+
+ *fugitive-:Glog*
+:Glog [args] Load all previous revisions of the current file into
+ the quickfix list. Additional git-log arguments can
+ be given (for example, --reverse). If "--" appears as
+ an argument, no file specific filtering is done, and
+ previous commits rather than previous file revisions
+ are loaded.
+
+ *fugitive-:Gllog*
+:Gllog [args] Like |:Glog|, but use the location list instead of the
+ quickfix list.
+
+ *fugitive-:Gedit* *fugitive-:Ge*
+:Gedit [revision] |:edit| a |fugitive-revision|.
+
+ *fugitive-:Gsplit*
+:Gsplit [revision] |:split| a |fugitive-revision|.
+
+ *fugitive-:Gvsplit*
+:Gvsplit [revision] |:vsplit| a |fugitive-revision|.
+
+ *fugitive-:Gtabedit*
+:Gtabedit [revision] |:tabedit| a |fugitive-revision|.
+
+ *fugitive-:Gpedit*
+:Gpedit [revision] |:pedit| a |fugitive-revision|.
+
+:Gsplit! [args] *fugitive-:Gsplit!* *fugitive-:Gvsplit!*
+:Gvsplit! [args] *fugitive-:Gtabedit!* *fugitive-:Gpedit!*
+:Gtabedit! [args] Like |:Git!|, but open the resulting temp file in a
+:Gpedit! [args] split, tab, or preview window.
+
+ *fugitive-:Gread*
+:Gread [revision] Empty the buffer and |:read| a |fugitive-revision|.
+ When the argument is omitted, this is similar to
+ git-checkout on a work tree file or git-add on a stage
+ file, but without writing anything to disk.
+
+:{range}Gread [revision]
+ |:read| in a |fugitive-revision| after {range}.
+
+ *fugitive-:Gread!*
+:Gread! [args] Empty the buffer and |:read| the output of a Git
+ command. For example, :Gread! show HEAD:%.
+
+:{range}Gread! [args] |:read| the output of a Git command after {range}.
+
+ *fugitive-:Gwrite*
+:Gwrite Write to the current file's path and stage the results.
+ When run in a work tree file, it is effectively git
+ add. Elsewhere, it is effectively git-checkout. A
+ great deal of effort is expended to behave sensibly
+ when the work tree or index version of the file is
+ open in another buffer.
+
+:Gwrite {path} You can give |:Gwrite| an explicit path of where in
+ the work tree to write. You can also give a path like
+ :0:foo.txt or even :0 to write to just that stage in
+ the index.
+
+ *fugitive-:Gwq*
+:Gwq [path] Like |:Gwrite| followed by |:quit| if the write
+ succeeded.
+
+:Gwq! [path] Like |:Gwrite|! followed by |:quit|! if the write
+ succeeded.
+
+ *fugitive-:Gdiff*
+:Gdiff [revision] Perform a |vimdiff| against the current file in the
+ given revision. With no argument, the version in the
+ index is used (which means a three-way diff during a
+ merge conflict, making it a git-mergetool
+ alternative). The newer of the two files is placed
+ to the right. Use |do| and |dp| and write to the
+ index file to simulate "git add --patch".
+
+ *fugitive-:Gsdiff*
+:Gsdiff [revision] Like |:Gdiff|, but split horizontally.
+
+ *fugitive-:Gvdiff*
+:Gvdiff [revision] Identical to |:Gdiff|. For symmetry with |:Gsdiff|.
+
+ *fugitive-:Gmove*
+:Gmove {destination} Wrapper around git-mv that renames the buffer
+ afterward. The destination is relative to the current
+ directory except when started with a /, in which case
+ it is relative to the work tree. Add a ! to pass -f.
+
+ *fugitive-:Gremove*
+:Gremove Wrapper around git-rm that deletes the buffer
+ afterward. When invoked in an index file, --cached is
+ passed. Add a ! to pass -f and forcefully discard the
+ buffer.
+
+ *fugitive-:Gblame*
+:Gblame [flags] Run git-blame on the file and open the results in a
+ scroll bound vertical split. Press enter on a line to
+ reblame the file as it was in that commit. You can
+ give any of ltfnsewMC as flags and they will be passed
+ along to git-blame. The following maps, which work on
+ the cursor line commit where sensible, are provided:
+
+ A resize to end of author column
+ C resize to end of commit column
+ D resize to end of date/time column
+ q close blame and return to blamed window
+ gq q, then |:Gedit| to return to work tree version
+ i q, then open commit
+ o open commit in horizontal split
+ O open commit in new tab
+ - reblame at commit
+ ~ reblame at [count]th first grandparent
+ P reblame at [count]th parent (like HEAD^[count])
+
+:[range]Gblame [flags] Run git-blame on the given range.
+
+ *fugitive-:Gbrowse*
+:[range]Gbrowse If the remote for the current branch is on GitHub,
+ open the current file, blob, tree, commit, or tag
+ (with git-web--browse) on GitHub. Otherwise, open the
+ current file, blob, tree, commit, or tag in
+ git-instaweb (if you have issues, verify you can run
+ "git instaweb" from a terminal). If a range is given,
+ it is appropriately appended to the URL as an anchor.
+
+ To use with GitHub FI, point g:fugitive_github_domains
+ at a list of domains:
+>
+ let g:fugitive_github_domains = ['git.example.com']
+~
+:[range]Gbrowse! Like :Gbrowse, but put the URL on the clipboard rather
+ than opening it.
+
+:[range]Gbrowse {revision}
+ Like :Gbrowse, but for a given |fugitive-revision|. A
+ useful value here is -, which ties the URL to the
+ latest commit rather than a volatile branch.
+
+:[range]Gbrowse [...]@{remote}
+ Force using the given remote rather than the remote
+ for the current branch. The remote is used to
+ determine which GitHub repository to link to.
+
+MAPPINGS *fugitive-mappings*
+
+These maps are available everywhere.
+
+ *fugitive-c_CTRL-R_CTRL-G*
+<C-R><C-G> On the command line, recall the path to the current
+ object (that is, a representation of the object
+ recognized by |:Gedit|).
+
+ *fugitive-y_CTRL-G*
+["x]y<C-G> Yank the commit SHA and path to the current object.
+
+These maps are available in Git objects.
+
+ *fugitive-<CR>*
+<CR> Jump to the revision under the cursor.
+
+ *fugitive-o*
+o Jump to the revision under the cursor in a new split.
+
+ *fugitive-S*
+S Jump to the revision under the cursor in a new
+ vertical split.
+
+ *fugitive-O*
+O Jump to the revision under the cursor in a new tab.
+
+ *fugitive--*
+- Go to the tree containing the current tree or blob.
+
+ *fugitive-~*
+~ Go to the current file in the [count]th first
+ ancestor.
+
+ *fugitive-P*
+P Go to the current file in the [count]th parent.
+
+ *fugitive-C*
+C Go to the commit containing the current file.
+
+ *fugitive-a*
+a Show the current tag, commit, or tree in an alternate
+ format.
+
+SPECIFYING REVISIONS *fugitive-revision*
+
+Fugitive revisions are similar to Git revisions as defined in the "SPECIFYING
+REVISIONS" section in the git-rev-parse man page. For commands that accept an
+optional revision, the default is the file in the index for work tree files
+and the work tree file for everything else. Example revisions follow.
+
+Revision Meaning ~
+HEAD .git/HEAD
+master .git/refs/heads/master
+HEAD^{} The commit referenced by HEAD
+HEAD^ The parent of the commit referenced by HEAD
+HEAD: The tree referenced by HEAD
+/HEAD The file named HEAD in the work tree
+Makefile The file named Makefile in the work tree
+HEAD^:Makefile The file named Makefile in the parent of HEAD
+:Makefile The file named Makefile in the index (writable)
+- The current file in HEAD
+^ The current file in the previous commit
+~3 The current file 3 commits ago
+: .git/index (Same as |:Gstatus|)
+:0 The current file in the index
+:1 The current file's common ancestor during a conflict
+:2 The current file in the target branch during a conflict
+:3 The current file in the merged branch during a conflict
+:/foo The most recent commit with "foo" in the message
+
+STATUSLINE *fugitive-statusline*
+
+ *fugitive#statusline()*
+Add %{fugitive#statusline()} to your statusline to get an indicator including
+the current branch and the currently edited file's commit. If you don't have
+a statusline, this one matches the default when 'ruler' is set:
+>
+ set statusline=%<%f\ %h%m%r%{fugitive#statusline()}%=%-14.(%l,%c%V%)\ %P
+<
+ *fugitive#head(...)*
+Use fugitive#head() to return the name of the current branch. If the current
+HEAD is detached, fugitive#head() will return the empty string, unless the
+optional argument is given, in which case the hash of the current commit will
+be truncated to the given number of characters.
