This is documented differently in the 3BSD manpage: 'so is documented to be ignored by soelim. Nothing is mentioned about spaces between . and so. But the implementaion of Bill Joys soelim recognizes only ".so", so the above written is true too. > Admittedly, this mechanism doesn't make much sense with other > preprocessors in general, but I think it's not a bad idea to stay with > this scheme for orthogonality: > > .XXX > > can be handled by a preprocessor, while > > .<whitespace>XXX > > is something only `troff' should process. Is this documented somewhere? Anyway--to put a preprocessor section into an .if block is of limited use, so it can be accepted not to allow this whitespace. Carsten
