They are the same.

Consolidated git_log and git_whatchanged; added git_show.

Minor requests from Junio: Consolidate the identical implementations of
git_log and git_whatchanged, especially since these two commands take
pretty much identical arguments.  This should make the completion package
a little easier to maintain.

Also added branch name completion for git-show.  I tried to implement
--pretty=oneline (etc.) but am apparently missing something as bash did
not want to complete it through the registered completion routine, so that's
still unsupported.
