Thanks.

You should really try to follow the GNU coding standards though.  The number
of formatting problems you introduced with your changes is significant --
enough that I'm not going to try and fix them all.

You should also include a more detailed ChangeLog entry.  The format is
	* file (function): What changed.

Do that for each file/function you change please.

Also, you need only send diffs.  We do not need a copy of your new file.
