Actually, the one feature I'd like (I think) is to be able to join 
together the empty commit mechanism and the cover letter mechanism 
within format patch so that:

* the empty commit message would detected and automatically become the 
[0/N] in the patch series (without need to say --cover-letter)

* the cover letter would still have some 'template' markings to say "*** 
insert what's changed here***" or smilar (with option to exclude them).

That way, when starting a series / branch, the first item would be to 
add the explanatory 'empty commit' that states the requirements of what 
one hopes to achieve (a key cover letter content), which is then 
followed by commits that move toward that goal.

The series can then be rebased as the user develops the code, and that 
cover note can be edited as required during the rebase.

When it comes time to show it to the list, the format patch will *know* 
from the empty commit that it is the [0/N] cover letter and 
(perhaps -option) add the appropriate markers ready for editing.

The user edits the cover letter with the extra 'what's changed' / 
interdiff / whatever, and sends. sendmail barfs if the user hasn't 
edited the markers.

This could also work with the sendmail patch formating (though I've 
never used that workflow) as now the cover letter becomes automatic for 
the upstream.
