Subject: Fix PL macro indentation when the entry spans a page break.  (Note to anyone

Fix PL macro indentation when the entry spans a page break.  (Note to anyone
who thinks these should be upgraded to keep an entry on a single page: look
at the footnote code in the original nroff docs, the tmac.n display code,
and then use ev 2 anyway - as long as there are no footnotes on a page with
PL, you might get away with it.)
