Comment (by mdawaffe):

 OK - I lied :)  There were a few issues on WP.com with back compat.  Also,
 a bunch of the plugins in http://pastie.org/pastes/2522893/text (thanks,
 duck_) use the matching groups in ways I didn't expect.

 So here's a new patch.

 It's the same as [attachment:15600.3.diff] with the following differences:
 * All matching groups are the same as in the current code.
 * The regex no longer requires {{{/x}}} to compile.

 I believe the patch is now 100% backward compatible.
