Make the exclamation mark (`!') a recognizable punctuation character.

Make the question mark (`?') a valid punctuation character.
One can now, for example, write:

.Sh EXAMPLES
Have you read the
.Xr mdoc 7 ?
.Pp
Do you like
.Fx ?

The mdoc.samples(7) page has been automatically updated to
record this change.

Fixed the `mysterious blank lines' problem. This was due to unconditional
use of the .ne requests. groff(1) apparently inserts some virtual trap at
the end of each page, and this was causing the .ne request to output extra
lines. Solution is to only use them in troff mode.

Also fixed a related bug in .It macros, where it would insert a page break
in the middle of a sentence.

Removed the end of page trap in nroff mode, as this causes .sp requests to
sometimes eat the space due to the nearby trap.

Removed blank line that appeared as the first line on each nroff-formatted
manual page.
