Edit: parenmatch.py

"""ParenMatch -- for parenthesis matching. 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.

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.
