        Since you refer to 3 keypad modes, I presume you are refering (sp?)
to the code with your own mods, which does not hide "hidden" links.  Since
they have no link name, if they're included in the 'l'ist menu their
addresses (URL, plus fragment if present) are used as the link name.  What
follows the bullet is a space.  The address has no spaces in it, so if it
would extend past the right margin, the wrap is triggered at the only space
on that first LI line, i.e., the one after the bullet.  Once that occurs,
there technically are no spaces (just the second-or-greater-line left
indentation), so you'll then get an arbitrary wrap at the right margin
within the address.  You could try replacing the space following the bullet
with an nbsp (in the code under case HTML_LI: in HTML_start_element() of
HTML.c, but that's very hairy code, so you should exercise such a mod for a
variety of list markup to be sure you didn't break something inadvertantly.

        Thank you for sharing you mere guess (which is wrong) about what
the fotemods code does, and how your guess sounds to you.  I don't see,
though, what useful purpose is served by posting that to the list.  If
you detect a bug in the fotemods code when actually using it, and have
confirmed by checking the FOTEMODS file at slcc that you have the latest
update, please do report the bug.
