Thanks, good catch.
But let me explain (also for everyone else interested in sending
patches) how you could produce the preferred patch format:
1. Commit your change(s) to you local git repository (e.g. via
'git commit -s -a' which commits all changes). You will be asked for
a commit comment, please provide a precise summary of the above.
2. Use 'git format-patch HEAD^..HEAD' to extract the patch in right
format and copy&paste it into your mail client (there are also other
ways like 'git send-email', but the latter is more transparent for
starters).
Please give this a try and I will happily apply the result.
Thanks again,
Jan
