This strips from the refname the common directory prefix with the

This is particular usefull for bash completion, to get refs without

Should this last sentence really belong to the documentation?

Furthermore, I think ':strip' better describes what this format
actually does.  Even you have used the word 'strip' in the commit
message and in the documentation as well.


As far as bash completion is concerned, I'm for it, as it does exactly
what the completion script needs to perform better, it doesn't have
those conceptual issues 'refbasename' has, and it's only a tad slower
than 'refbasename'.

However, if we consider possible use cases other than bash completion,
I don't know which one is more useful.  For example, if you have two
branches 'foo/bar' and 'foo/baz', then 'git merge $(git for-each-ref
--format=%(refbasename) refs/heads/foo)' will work as expected, but
'refname:short' not, as it will output only 'bar' and 'baz' which 'git
merge' can not find.
