I noticed that automake's contribution guidelines suggest using
"git describe" output in commit logs to reference previous commits.
By contrast, in coreutils, I had acquired the habit of using a bare SHA1
prefix (8 hex digits), since gitk creates clickable links for that, and
not for "git describe" output.
I prefer the readability of the full "git describe" output, yet want to
retain the gitk links, so wrote the following that renders as clickable
not just SHA1-like strings, but also an SHA1-like string that is
prefixed by "-g".

This is relative to master.
Think of this as mere proof-of-concept:
Ideally, the string preceding the -g would be used to disambiguate
the SHA1 prefix, but that would require more code.
I confess that I haven't looked to see if documentation needs
to be updated or if this would merit test suite additions.
