`Dl` marks a single line as 'literal'. Since we don't output single
lines differently in literal vs regular mode (we only insert line
breaks for multi-line blocks in literal mode), we can just skip it.
When encountering an `Ns` mdoc macro ('no space') inside an `Ic` block
('command'), such as for 'lines=number' in ssh-keygen.1, `mdoc2man`
just output the macro instead of processing it.
This adds processing for `Ns` when seen inside an `Ic` block.
I noticed the square brackets in `destination [command [argument...]`
in the synopsis for the `ssh.1` manpage were not balanced,
this balances them.
