managen: fix superfluous leading blank line in quoted sections

When a markdown quoted section using 4-space indentation was converted
to nroff, managen previously caused a newline to appear after the
leading .nf. This fix makes sure that newline is inserted *before* .nf
as intended.

This is perhaps most notable in the HTML version of rendered manpages if
the quoted sections use different colors or similar.

Closes #14732
