Begin cleaning up scaling units.

Start with the horizontal terminal specifiers, making sure that they match
up with troff.
Then move on to PS, PDF, and HTML, noting that we stick to the terminal
default width for "u".
Lastly, fix some completely-wrong documentation and note that we diverge
from troff w/r/t "u".
