Subject: Add a performance test for git-grep
X-Git-Tag: v1.7.10-rc0~56^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=134593c8ca1866bfbb0c63506f350ce9868fd7e5;p=git.git

Add a performance test for git-grep

The only catch is that we don't really know what our repo contains, so
we have to ignore any possible "not found" status from git-grep.
