[Groff] Odd problem escaping `.'

[Louis Guillaume]

Hi,

I'm looking for a way to get my section numbers in the table of
contents. This is with -ms.

This is what I've been trying:

.NH 1
OVERVIEW
.XS
\n[H1]
\.\n[H2]
\.\n[H3]
OVERVIEW
.XE


The above produces...

1 OVERVIEW . . . . . . . . . . . . . . . . . . . . . . . . . . . .  1

... in the table of contents. Why does it not produce:

1.0.0.0 OVERVIEW . . . . . .

???

If I try to escape the `.' at the beginning of the line further like...

\\.\n[H2]

... I get `1\.0\.0\.0' which is just strange.


Any help would be great, thanks!

Louis
