That's really weird, I'm not sure what's going on. One thing that would 
be useful would be to check whether the output of

git log --pretty='%s' --reverse 08487eea68a2fa5..

includes the stray 'p' or not. I had a look through the configure output 
you attached to your previous mail and it seems you're building without 
iconv and gettext support, I've built git on linux with
make NO_ICONV=1 NO_GETTEXT=1
to try and test that and the rebase todo list was fine. Building with 
configure rather than the Makefile that comes with git can be a bit 
flaky sometimes as occasionally when a new compile option gets added to 
the Makefile updating the configure script gets overlooked but I don't 
know if that is the problem here or not.

Best Wishes

Phillip
