The CREDITS file does not have an uniform style. Some entries use tabs and some other use whitespace. This patch replaces al tabs with withespace and aligns all names and emails.
That patch doesn't apply to the current top-of-trunk - and it's a big patch with one hunk, so that means that *none* of it applies automatically. Could you regenerate it based on the top-of-trunk?
You are right. Sorry about that. I just assumed that the credits file would not had changed since 1.1.1. I attach a new version of the patch.
Checked into the main and 4.1 branches and pushed.
