[Groff] pic and nroff

[Joerg van den Hoff]

I seem to recall that once upon a time simple pic output was reasonably
approximated with nroff (i.e. groff -Tlatin1).

at least I'm rather sure that some 2 years ago it was always possible to look at
the actual text of larger documents containing interspersed `pic' code with
nroff without problems. at some point that behaviour changed: I now encounter
the situation where the `nroff' output starts to switch the background colour to
black (or whatever: there are black rectangles instead of readable text) after
it encounters some pic code in the document.

as an example I've included a simple example. if you format this with

pic tt.ms | nroff -ms

you should see what I mean (and this is one of the more benign cases: a bit
of the pic output is still recognizable).


question: 
has something been broken with the nroff approximation of pic (or do I
phantasize and it was never there?).

what about the "censoring" of the document text?
