That shouldn't be too hard.  checkpatch has been subscribed since birth
but short circuiting the replies to me only.

I guess the main question is whether to reply-all or reply just to the
sender when commenting on patches.  Perhaps for the sanity of the rest
of the world, just the sender makes most sense.

It should pick up both of these, the word-wrapping is already there as
we detect lines within patch segments which don't start '[ +-]', the
tab-expanded should be picked up as every line would be "don't use
spaces use tabs for indent".
