2540	"[Text.Regex] incorrect word boundary (""\\b"") substitutions. Bug in regex-compat's subRegex handling of BOL flags."	Eelis-	ChrisKuklewicz	"Consider:
{{{
  import Text.Regex
  main = putStrLn $ subRegex (mkRegex ""\\b(.)"") ""abcdef"" ""|\\1""
}}}
This outputs ""|a|b|c|d|e|f"", while it really should output ""|abcdef"" (at least according to Perl and Ruby).
