[PATCH] GIT-VERSION-GEN: detect dirty tree and mark the version accordingly.

From: Junio C Hamano <junkio@cox.net>
Date: Jan 10, 2006, 02:53 UTC
Message-ID: <7vlkxobxpg.fsf@assigned-by-dhcp.cox.net>

If we are building from a working tree with local modifications, mark the version accordingly.

Deliberately uses '-' to prevent RPM from being built from such a tree.

Signed-off-by: Junio C Hamano <junkio@cox.net>

 * This is a useful precaution and should be safe, so planned to
   go into 1.1.1.
