I’ve updated the Curly Quotes for Movable Type script in response to two points made by John Gruber. It was interesting to be referred to by last name only, so I felt the need to respond as soon as I read the criticisms. The issues identified, namely the inability to quote single letters like “a” and a small whitespace bug which affected a valid but rarely seen method of writing tags, were trivial to fix. I am still a firm believer in a faster pure regular expression solution to this particular problem; with a good enough regular expression you can parse anything :). Thanks to John for pointing these out.
