Ah — I completely missed this point! Maybe a bit of occasional cargo-culting isn't entirely bad. :)

I still think I would use (?<! \S) (?! \S) as boundary assertions instead of \b though, to properly handle "words" like 'a1-b1'. Anon gives no hint that such things may appear in the data, but an abundance of caution inclines me this way. More reflex defensiveness I guess.

Give a man a fish:  <%-{-{-{-<
