[RFC PATCH 4/4] Add a performance test for git-grep

From: Thomas Rast <trast@student.ethz.ch>
Date: Dec 14, 2011, 15:23 UTC
Message-ID: <370de2c5c277513098480baf47f73ca6077787b0.1323876121.git.trast@student.ethz.ch>
In-Reply-To: <cover.1323876121.git.trast@student.ethz.ch>

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.
