I do not think you would want this non-patch cruft seen at the apply
layer at all.  Reading a mailbox, with the help of mailsplit and
mailinfo, and being the driver to create a series of commits is what
"am" is about, and it would have to notice that the non-patch cruft
at the beginning is not a patch at all and defer creation of an
empty commit with that cover material at the end.  For each of the
other messages in the series that has patches, it will need to call
apply to update the index and the working tree so that it can make a
commit, but there is NO reason whatsoever to ask help from apply, whose
sole purpose is to read a patch and make modifications to the index
and the working tree, to handle the cover material.
