I wrote a script to parse the two things that it is trying to compare, from the assert output. FETCH_HEAD right now has 813 lines. The output of git fetch, when I run it manually on the command line (I have not been able to figure out exactly what command it is running, but I'm assuming it'sgit fetch --all -v - is this correct?) has also 813 lines if you ignore the first two lines:Fetching origin andFrom github.com:org/repo

However, the very last 4 branches in FETCH_HEAD are missing in the GitPython fetch output, the last of which is this line:

a3a81646dd65dfa4b4412c0f3a5fd4183cbaa2e5 not-for-merge branch 'zendesk' of github.com:org/repo

It can't find the matching line in the fetch output (or for the previous 3):

= [up to date] zendesk -> origin/zendesk

Even though I see the above lines when I dogit fetch --all -v, I don't see the last 4 lines in the GitPython assert output. Let me know if you need more info. Is there possibly some length limit? I'm using git 1.8.3.4.

BTW I was using GitPython==0.3.2.RC1 prior to this and it was still failing an assertion, although I'm not sure the assertion was exactly the same.
