Subject: Discard stderr output from git-rev-parse
X-Git-Tag: v0.14~54
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/d9d460a1eef90a883584d07b840f89ccdd332d45

Discard stderr output from git-rev-parse

This gets rid of the annoying "fatal: Needed a single revision"
messages that were printed in addition to StGit's own error message.
