Prevent os.path.relpath from converting "./input" to "input".

Fixes #3034.

kyleam added 3 commits Nov 30, 2018
Convert normalize_hits to operate on a single hit rather than a list
of hits.  Working on a list makes sense to avoid repeating the
sorted() call, but the normalization logic is going to get an extra
condition, and it will be easier to work with a single hit.  We could
also add another helper function to avoid repeating sorted(map(...)),
but that's an overkill.
Subdirectory globbing is already covered a bit in the run tests, but
add some more tests that will be useful for testing the next commit.
When globbing inputs/outputs, we normalize them by making them
relative to the directory the command will run in.  In the eyes of
os.path.relpath(), the "./" on "./path" is superfluous, and it drops
it.  This is usually OK, but a datalad run caller may rely on it to
format a script call:

    datalad run --input=./script {inputs} ...

Fix this by returning the hit unchanged if the normalized version
looks the same, sans the current directory prefix.  It's possible that
there is an edge case that this misses, but it's simple, should catch
the main cases, and shouldn't result in any false positives.

Closes datalad#3034.

 A variety of bugfixes and enhancements

 ### Major refactoring and deprecations

 - All extracted metadata is now placed under git-annex by default.
   Previously files smaller than 20 kb were stored in git. ([#3109])
 - TODO: get_runner #3104 and pending #3131

 ### Fixes

 - Improved handling of long commands:
   - The code that inspected `SC_ARG_MAX` didn't check that the
     reported value was a sensible, positive number. ([#3025])
   - More commands that invoke `git` and `git-annex` with file
     arguments learned to split up the command calls when it is likely
     that the command would fail due to exceeding the maximum supported
     length. ([#3138])
 - The `setup_yoda_dataset` procedure created a malformed
   .gitattributes line. ([#3057])
 - [download-url] unnecessarily tried to infer the dataset when
   `--no-save` was given. ([#3029])
 - [rerun] aborted too late and with a confusing message when a ref
   specified via `--onto` didn't exist. ([#3019])
 - [run]:
   - `run` didn't preserve the current directory prefix ("./") on
      inputs and outputs, which is problematic if the caller relies on
      this representation when formatting the command. ([#3037])
   - Fixed a number of unicode py2-compatibility issues. ([#3035]) ([#3046])
   - To proceed with a failed command, the user was confusingly
     instructed to use `save` instead of `add` even though `run` uses
     `add` underneath. ([#3080])
 - Fixed a case where the helper class for checking external modules
   incorrectly reported a module as unknown. ([#3051])
 - [add-archive-content] mishandled the archive path when the leading
   path contained a symlink. ([#3058])
 - Following denied access, the credential code failed to consider a
   scenario, leading to a type error rather than an appropriate error
   message. ([#3091])
 - Some tests failed when executed from a `git worktree` checkout of the
   source repository. ([#3129])
 - During metadata extraction, batched annex processes weren't properly
   terminated, leading to issues on Windows. ([#3137])
 - [add] incorrectly handled an "invalid repository" exception when
   trying to add a submodule. ([#3141])
 - Pass `GIT_SSH_VARIANT=ssh` to git processes to be able to specify
   alternative ports in SSH urls

 ### Enhancements and new features

 - [search] learned to suggest closely matching keys if there are no
   hits. ([#3089])
 - [create-sibling] gained a `--group` option so that the caller can
   specify the file system group for the repository. ([#3098])
 - Interface classes can now override the default renderer for
   summarizing results. ([#3061])
 - [run]:
   - `--input` and `--output` can now be shortened to `-i` and `-o`.
     ([#3066])
   - Placeholders such as "{inputs}" are now expanded in the command
     that is shown in the commit message subject. ([#3065])
   - `interface.run.run_command` gained an `extra_inputs` argument so
     that wrappers like [datalad-container] can specify additional inputs
     that aren't considered when formatting the command string. ([#3038])
   - "--" can now be used to separate options for `run` and those for
     the command in ambiguous cases. ([#3119])
 - The utilities `create_tree` and `ok_file_has_content` now support
   ".gz" files. ([#3049])
 - The Singularity container for 0.11.1 now uses [nd_freeze] to make
   its builds reproducible.
 - A [publications] page has been added to the documentation. ([#3099])
 - `GitRepo.set_gitattributes` now accepts a `mode` argument that
   controls whether the .gitattributes file is appended to (default) or
   overwritten. ([#3115])
 - `datalad --help` now avoids using `man` so that the list of
   subcommands is shown.  ([#3124])
