When you hit a right paren, the cursor should move briefly to the left
paren.  Paren here is used generically; the matching applies to
parentheses, square brackets, and curly braces.

    """Highlight matching openers and closers, (), [], and {}.

There are three supported styles of paren matching.  When a right
    paren (opener) is typed:

opener -- highlight the matching left paren (closer);
    parens -- highlight the left and right parens (opener and closer);
    expression -- highlight the entire expression from opener to closer.
    (For back compatibility, 'default' is a synonym for 'opener').

Flash-delay is the maximum milliseconds the highlighting remains.
    Any cursor movement (key press or click) before that removes the
    highlight.  If flash-delay is 0, there is no maximum.

TODO:
    - Augment bell() with mismatch warning in status window.
    - Highlight when cursor is moved to the right of a closer.
