[Groff] Headers in MM

[Anton Shepelev]

Hello all,

When  I saw how MM formats headers the first thing
that stroke me was the lask of hanging indent  for
multiline headers, so I did these little modifica-
tion:

      .de HY
      .length a \*(}0
      .in +\nan
      .ti -\nan
      .nr ;0 2
      ..
      .de HZ
      .in 0n
      ..

It produces headers like this:


1.  This is a very long hearer. Note the hanging
    indent.


I'd like to ask you whether this  modification  is
ideologically correct and whether it won't produce
undesirable side effects.

Thank you in advance,
Anton
