My guess is that it has to do with Bash 4, the equal sign must be seen
as a new word. I'm running Ubuntu 10.04 and have the same problem.
I fixed the problem locally, I just don't know if that works on Bash 3
and I doubt it will work on Bash 3.

I changed the script only for git log, not other commands yet, like 
git am --whitespace=<tab><tab>
