!~FILENAME~:! !DELIM macros for moving over []{}<>(), etc.  To make other
characters delimiters, run MAKE DELIMITER PAIRS and assign ^R MOVE OVER
DELIMITERS to control, meta, or control-meta slots for the delimiter
characters.  For example:
    MM Make Delimiter Pairs<>
    M.M^R Move Over Delimiters U.<
    M.M^R Move Over Delimiters U.> will make C-< and C-> move back and
forward (respectively) over <> Use UNMAKE DELIMITER PAIRS to undo this.

Also sets up FS ^R Paren to do the right thing.  !

!Make Delimiter Pairs:! !C Define entries in the Delimiter ..D Table
for balanced pairs of delimiters.  The string argument should be
an even number of characters, paired.  Note that the delimiter
characters must have ^R Move Over Delimiters  assigned to one
of their ^R macro slots (control, meta, or control-meta - but
not TOP).!
