[Groff] Hanging headings in MS

[Anton Shepelev]

Hello all,

Is it possible to modify the MS macro package
(by adding some macro (re)defintions) so it
would make all headings stick out to the left
by the same abount of space?

1. Heading One

  text text
  text text

1.1 Heading One.one

  text text
  text text
  text text

2. Heading Two

  text text
  more text
  
I can emulate such behaviour using .RS .. .RE but
I'd like to make it automatical.

Of all the standard packages, MS is the closest to
my needs and this is the only change that has to
be done.

Thanks in advance,
Anton
