Fix github-merge with git version 2.1.0

[gavinandresen]

Running git version 2.1.0 on OSX (homebrew), I get
fatal: '1q': not a non-negative integer

I'm guessing git command-line parsing got more strict recently?

This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly. If you are waiting on a test, please check timestamps to verify that the test.log is moving at http://jenkins.bluematt.me/pull-tester/current/
Contact BlueMatt on freenode if something looks broken.

Heh, I can't even find a -q in the documentation for git log.

Looks like for git -q in general means 'quiet mode' mode, but I cannot find it documented for git log anywhere either.
Anyhow - I'm going to use the new version of the script to merge this, and if that works, ACK.
