Put the prefix-underline-drawing away into it's own function so we can
see what is happening. This is the last stage of reformating; the next
patches will actually start altering behaviour.
(Trivial change in behaviour; if we accidentally underline something that
was ellipsified out the underline will now be the size of the underlined
character rather than the character that would have been underlined, which
shouldn't be underlined anyway)
