Subject: GIT-VERSION-GEN: Don't include output of git update-index.
X-Git-Tag: v0.5.1~12^2~9
X-Git-Url: http://git.tuebingen.mpg.de/?a=commitdiff_plain;h=d6cf71afbc470b86d51645750b8214791ad9a4c2;hp=d6cf71afbc470b86d51645750b8214791ad9a4c2;p=paraslash.git

GIT-VERSION-GEN: Don't include output of git update-index.

GIT-VERSION-GEN calls git update-index which might write something
like "configure.ac: Needs update" to stdout. We don't want this text
to be part of the version string, so make sure we discard the output
of git update-index.
