The groff manual says: .rs Restore spacing; turn no-space mode off.
However,
.rs
.sp 3
does not work; one has to output some text first, to get .sp to work.
Is this a bug in groff, or in its documentation?
What is the rationale for this behaviour?
About the .nop request:
.nop anything
Always process anything.
What is this request good for?
Kind regards
