Entering the widest glyph literally rather than its width, which
would have to be calculated, makes things simpler. Furthermore, if
the glyph is in double-quotes, users can add space to or subtract
it from the gutter between the enumerators and the text with \*[FWD dist].

If you remove the two 'if' clauses,
.LIST RETURN
spits out
[mom]: You must append a number to the RETURN argument to LIST.
because an initial letter R is checked for in order to process
ROMAN<n> and roman<n> lists.
Apply the attached, revised patch and test. Variable enumerator
lists are entered with, for example,
.LIST VARIABLE \[en]
Mom calculates the width of the en-dash and adds the same
unbreakable and unpaddable space used as a gutter for all other
enumerator types.
