respond inline to attached patch?

[Xu Wang]

Hello,

I sometime receive a message with an attached patch. I would like to
make a comment on a couple of lines in the patch. Is there easy way to
respond such that basically their attached patch is part of their
message so easier to make my comments in-line?

I can do this manually by opening the patch, pasting into mutt and
putting the ">" things. but I am hoping for even lazier :)

Kind regards,

Xu
