I cannot seem to be able to find related discussions around that
patch, so this is only my guess, but I suspect that this is to
discourage people from doing something like:
refs/tags/*:refs/tags/foo-*
which would open can of worms (e.g. imagine you fetch with that
pathspec and then push with refs/tags/*:refs/tags/* back there;
would you now get foo-v1.0.0 and foo-foo-v1.0.0 for their v1.0.0
tag?) we'd prefer not having to worry about.
