There seems to be a "round trip" problem when editing function definitions
within the definition pane of the function window.
If the function text uses single quotes (') then these must be doubled up
(because of the single quotes enclosing the entire function body). However
the doubling up is removed in a save/display loop.
The result is that _every time_ you edit the function you have to add an
extra quote to each occurence of the quote character.
