Create a better reflog. Follows the discussion in
https://lore.kernel.org/git/akZfm-igZKeHaDST@pks.im/.

"git reflog" lists every step of a rebase and every branch switch, which
makes it hard to see what was done and on which branch. This adds two
options to "git reflog" and "git log -g":

 * --operations shows one entry per command, folding a rebase into the entry
   that finished or aborted it, and leaves out entries that change no
   branch.
 * --historical-branch decorates each entry with the branch HEAD was on when
   it was recorded.

Harald Nordgren (3):
  reflog: name the strings that mark switches, renames and rebase steps
  reflog: add --operations to show one entry per command
  reflog: add --historical-branch to name the branch of each entry
