This get_commit_buffer() may allocate a fresh buffer...

...and then this return leaks the result (the other code path hits
unuse_commit_buffer(), and is fine).
This leak was noticed by Coverity. It has a _ton_ of false positives
across the whole project, but it sends out a mail with new ones every
few days, which is usually short enough that I can process it in 30
seconds or so.
I _think_ that email just goes to me and Stefan right now. You can add
yourself at:
https://scan.coverity.com/projects/git?tab=project_settings
if you already have admin access to the project (which I think you
(Dscho) do). I wonder if it would be helpful to send that output to the
list.
