When an ancient "git" that does not understand "describe" command is on the $PATH, "git describe" emitted a Usage message without exiting non-zero status (which is a mistake we cannot fix retroactively). Catch this case to make sure we do not try using phoney multi-line string as a version number. Signed-off-by: Junio C Hamano <junkio@cox.net>
