24.3.50; Elisp manual: mention what units are used for window margin functions |

(elisp) `Display Margins` talks a lot about window margins, but AFAICT
it never once says which units are used for the functions and variables
described there. I'm guessing the unit is `frame-char-width', but Emacs
should tell us explicitly here.
Moreover, we don't even tell users what a nil value means, as opposed
to a whole number.
For example, right now, `M-: (window-margins)' returns `(nil)' for me,
which corresponds to both LEFT and RIGHT being nil. What does a nil
value mean for each of these?

Done.
