It'd be nice to pass this through `git rev-parse --short` or maybe even 
`git describe --always --all`. vc-git.el could also use something like 
this when it gets the ref for the modeline (see 
'vc-git-mode-line-string' and 'vc-git--symbolic-ref').

In fact, maybe there should be a generic VC function for getting a 
"friendly" string describing a commit. Then code could use that function 
in some/most cases instead of showing the full commit ID.
