git-version-gen: Fix for tags containing '-' Really old versions of git-describe (before v1.5.0, Feb 2007) don't have the number of commits in their long format output, i.e. where modern 'git describe --abbrev=4 --match="v*"' prints "v0.1-1494-g124b9", they print "v0.1-1494-g124b9". git-version-gen recognizes both patterns, and normalizes the old format to the new one. Unfortunately, this normalization code gets confused when the tag contains '-'. Reproducer: $ git-tag -m test v0.2-rc1 $ build-aux/git-version-gen .tarball-version; echo build-aux/git-version-gen: WARNING: git rev-list failed UNKNOWN We take exact tag "v0.2-rc1" for the old format, extract the presumed tag "v0.2" from it, then run "git rev-list v0.2..HEAD" to count commits since tha tag. Fails, because tag "v0.2" does not exist. * git-version-gen: We could perhaps drop support for versions from more than a decade ago. But tightening the pattern match is easy enough, so do that. Still breaks when you use version tags ending in something matching -g????, but you arguably get what you deserve then.
