Merge from OpenBSD right after 1.10.6; now back to full sync.

* mdoc.c: blank lines outside literal mode are more similar to .sp than .Pp
* backslashes do not terminate macros; partial revert of mdoc.c 1.164;
  the intention of that commit is fully achieved in roff.c
* mdoc_term.c: no need to list the same prototype twice
* mdoc_validate.c: drop .Pp before .sp just like .Pp before .Pp
* fix off-by-one found by jsg@ with parfait, OpenBSD term_ps.c 1.12
