So, suppose we change this. Really, what I should have written is:
[[
.TH xxx 2 yyyyy zzzzz
.TP
XXXXXXXXXX
.RS <----- I moved this .RS
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do
eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut
enim ad minim veniam, quis nostrud exercitation ullamco laboris
nisi ut aliquip ex ea commodo consequat.
.PP
.RS +4n
.EX
int
main(int argc, char *argv[])
{
return 0;
}
.EE
.RE
.RE
]]
So, any time we have a .TP block that might have inline code (or
perhaps just multiple paragraphs), then the proposal is that we write
[[
.TP
HEADWORD
.RS
...
.RE
]]
But, what about the .TP blocks that contain just a single paragraph
and no inline code? Do we omit the .RS/.RE? That's a little
inconsistent and possibly confusing. On the other hand, if we add the
.RS/.RE to such blocks, that's a lot of clutter. Do you see what I
mean? It looks like there's no simple answer here.
Thanks,
Michael
