sys_nerr should come from standard headers -- not from a coder's guess
of what is right.

mdoc(7) police:

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

mdoc(7) police: removed leading whitespaces that are not inside
Bd/Ed; these hardly degrade the quality of the produced output.

Prepare for mdoc(7)NG.

Fix a couple of mdoc errors.

Don't refer to non-existent automount(8).
