From c96c29093f70f04e01ff1d3a9c1d509ef6afdb00 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 8 Aug 2006 13:11:16 -0700 Subject: [PATCH] GIT-VERSION-GEN: adjust for ancient git 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.
