[Groff] .ss problem

[Werner LEMBERG]

I've identified the bug which caused the incorrect formatting of
Thomas's example: The .ss request is handled incorrectly in
compatibility mode.

Before fixing, a general question.  In Unix troff, .ss is ignored if
in nroff mode.  Shall GNU troff behave identically if compatibility
mode is on?  Does it really make sense to `cripple' GNU troff for
compatibility reasons?

Opinions please.
