--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Even the git gcc-descr --full output can be shortened, use fewer sha digits if you want, and the non---full output is something meant for the subjects, r10-1234 is unique, will be redirected to the right commit in gitweb by our redirectors and is shorter than g: followed by 123456789abc.
