Mechanically kill hard sentence breaks and double whitespaces.

mdoc(7): Moved #include directives into the SYNOPSIS section.

Hiten's patchset for section four manpages, slightly edited by me.

mdoc(7) police: Use the new .In macro for #include statements.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...
