Just reviewed the patch myself and here in commit.c we should have a
localized version, right?
Should I resend the patch with the localisation or could you just amend
that?

[PATCH 2/2] prepare_revision_walk: Check for return value in all places

2014-08-10 Thread Stefan Beller
Even the documentation tells us:
You should check if it
returns any error (non-zero return code) and if it does not, you can
start using get_revision() to do the iteration.

In preparation for this commit, I grepped all occurrences of
prepare_revision_walk and added error messages, when there were none.
