Some people may find it convenient to append a simple patch at the
bottom of a discussion e-mail separated by a "scissors" mark, ready
to be applied with "git am -c". Introduce "--inline-single" option
to format-patch to do so. A typical usage example might be to start
'F'ollow-up to a discussion, write your message, conclude with "a
patch to do so may look like this.", and
\C-u M-! git format-patch --inline-single -1 HEAD <ENTER>
if you are an Emacs user. Users of other MUA's may want to consult
their manuals to find equivalent command to append output from an
external command to the message being composed.
It does not make any sense to use this mode when formatting multiple
patches, or to combine this with options such as --attach, --inline,
and --cover-letter, so some of such uses are forbidden. There may
be more insane combination the check in this patch may not even
bother to reject. Caveat emptor.

* I did this as a lunch-time hack, but I'll leave it to interested
readers as an exercise to find corner case "bugs", e.g. some
insane combinations of options may not be diagnosed as usage
errors, and to update the tests and documentation.
Personally, "git format-patch --stdout -1 HEAD" with manual
editing is more flexible, so I am not interested in spending
cycles to polish this further myself.
The preliminary patch 1/2 I sent earlier is worth doing, though.
