The purpose of the macro is to create a hanging indent. To illustrate, I'll format this very paragraph with a hanging indentation. You can see that lines after the first are indented, but the first is not. But it is still a paragraph, so inter-paragraph space precedes it. > It's being called as '.HP 0.2i'.

I'm not seeing a difference in vertical space among the 3 PDF exhibits. Each BNF declaration gets a paragraph. The break for "scheme" happens way too early, but that too is consistent among the 3 PDF exhibits. > It's used in the synopsis; it should be easy to distinguish. > > Is that some 1.23.0 regression maybe? > > In fact, after formatting with /usr/bin/groff (the old 1.22.4), I > don't see the effects of 1.23.0, so it's a regression. Is it known? Could you maybe take a screenshot and mark up the thing I'm supposed to be seeing with a big red arrow or something? > Attached you can see some PDFs of the page: > > uri.7.pdf > Original uri.7, formatted with groff-1.23.0 > > uri_PP.7.pdf > I edited the original uri.7 to use PP instead of HP, > and formatted with groff-1.23.0. > > uri_old.pdf > Original uri.7, formatted with groff-1.22.4. None of them look erroneous to me. Regards, Branden
