produces a 0-byte long patch. git-format-patch HEAD^ produces an 
error, whereas with more than one commit it produces tha last patch. 
Yes, I know about "--root" and that it does allow to extract the 
very first commit.

What version of git are you using? I believe the 0-byte diff has been 
fixed since git 1.6.1.1.

Mine is still 1.5.4, if it's already fixed in the meantime - all the 
better!

There is the off-chance that somewhere in those 3127 commits between 
v1.5.4 and v1.6.1.1, not only this bug is fixed.  You might be surprised 
;-)

Seriously again, in a project that moves as fast as Git, you should always 
test with a recent version, and v1.5.1 -- being over one year old -- does 
not account for recent.

Sorry, didn't mention, I also tested with 1.6.0.6 - still was there.

Thanks
