Hi Jeff,

I just found out that guilt does not yet support binary patch
capability git has for a while.

so, before I leave my office, I just tried guilt with this one liner.
the result was:

 - my local test with biniary files work (pop/push was check with md5), and
 - all regression test completed without any error

I felt that I just send it out. :-) 

# Note: I've googled "guilt bianry" before sending this but could not
# find any.  I'm not following nether git nor guilt development for a
# while. so, let me know if I'm off track.

thanks,
