Would it be a useful option to git-show-branch

In practice, probably 30 or so bits prefix would identify an
object uniquely within a repository, so one possibility is to
use the first 7 or so letters from 40-byte SHA1, after making
sure 7 is enough for that particular prefix -- otherwise use
more for that particular object.

The current "relative to the head" notation is descriptive and
easier to see when you do not have too many branches and complex
merge structure but one major drawback is that it is not stable;
you add a commit then what was used to be master~5 now suddenly
become master~6.
