I use:
	git format-patch -k -M

If you read the man page for git format-patch, you will see why "-D"
does not work at all for this, and this is why I can't apply these
patches, you are giving me something that is _known_ to not apply:

      -D, --irreversible-delete
	   Omit the preimage for deletes, i.e. print only the header but
	   not the diff between the preimage and /dev/null. The
	   resulting patch is not meant to be applied with patch nor git
	   apply; this is solely for people who want to just concentrate
	   on reviewing the text after the change. In addition, the
	   output obviously lack enough information to apply such a
	   patch in reverse, even manually, hence the name of the
	   option.

Yes, but you did it this way:
	[RESEND][PATCH 02/XX]
and git will just strip off the first [] chunk when applying it.  So
unless I wanted the [PATCH...] portion in the changelog, I had to delete
it by hand.

You can do:
	[RESEND PATCH 03/XX]
and all would be almost ok, but when I sort the emails, it would break
order.

So best is:
	[PATCH 03/XX RESEND]
if you really need the RESEND comment.  Personally, I would only do that
in the [00/XX] patch as that's what counts here.  You aren't resending
because I ignored them, but because there was a problem with them, so
you know I didn't apply those original ones.

hope this helps,
