A bit of a look at the source (pattern.c, function msg_search) shows that
the search is pretty simple; searching headers and message body is the
same code. The search function goes to the right place (start of header
for a header search, start of body for a body search, start of header
for searching both) and computes a search length (length of headers for
just header, length of body for just body and length of both for both),
and then simply does a line-by-line search of the text spanned.
So there's not special multiline mode for a header search, and no trivial
way to make one.
At least now you know why it behaves as it does.
