git format-patch -1 sha generates first commit on log instead <sha commit> reference

[kirotawa]

git.format_patch('-1 some_sha_commit') is getting the first commit in log and put it in a .patch file, but the correct is to get the commit by sha parameter, as in git command line: git format-patch -1 <sha_number>

versions tested: 0.3.6.

Is it a bug or I'm doing it wrong?

It's not a bug, correct way to execute it is: git.format_patch(-1, <sha_number>,other param...)
