doc/meref.me.in: Fix content nit and clarify.
Margin register values do not depend on the selected font (family). In
fact they don't depend on anything. They're always vees reckoned
against a vertical spacing of 120% of a 10 point type size. You can't
override this with command-line register settings. You can only change
them after the package initializes.
Clarify that vertical spacing is reset by paragraph macros (e.g., `lp`
-> `@p` -> `sz`); introduce that concept and the new `tv` register much
earlier accordingly.
