git/GIT-VERSION-GEN
Junio C Hamano 9b88fcef7d Makefile: use git-describe to mark the git version.
Note: with this commit, the GIT maintainer workflow must change.
GIT-VERSION-GEN is now the file to munge when the default
version needs to be changed, not Makefile.  The tag needs to be
pushed into the repository to build the official tarball and
binary package beforehand.
