All right, makes sense, but updating the git alias doesn't work for me.
Thus I'm suggesting a Python replacement of it, which does:

$ ./describe.py basepoints/gcc-11

r11-0-g50ee04838efc16


$ ./describe.py

r12-4285-g07dd3bcda17f97


$ ./describe.py --short

r12-4285


$ ./describe.py --full

r12-4285-g07dd3bcda17f97cf5476c3d6f2f2501c1e0712e6


Motivation behind usage of Python:
- the script can be put to contrib and nobody would have to re-run contrib/gcc-git-customization.sh locally
- it's not a single line script and one doesn't have to do bash escaping in the contrib/gcc-git-customization.sh script
- positional argument support

Thoughts?

Note I can port the same way the counterpart script.
One another note:

$ git gcc-descr basepoints/gcc-11

r11-0


seems to me like bogus.

Cheers,
Martin
