Fix some mark-up.

Fix the use of <replaceable> mark-up when used in conjunction with
<option>. Add a missing space before an option.

in order to avoid re-building the book when nothing has changed. (This
change was not intended to be part of this commit.)

Add short options after using long options in prose, per HACKING.
