Hi David,
Thanks for cleaning up the original code. It seems to be working well now. I'm using Textile all the time: http://foliovision.com/2011/11/08/textile-editing-bbedit
Thanks!
Have a good evening.
Making the web work for you, Alec

I'm no longer maintaining this at all, as I rarely use Textile any more. You're right about the glyph bugs, though — I don't know how I missed that!
I saw your fork and I'll add note in the header comment explaining that yours is now the canonical version. Thanks!
