Thanks Tom. I looked at the code in the libraries I referred to earlier, and it looks like the code in the regex
directoryis exactly the same as Walter Waldo's version, which has at least one comment from the middle of last decade
(~2003). Has people thought about migrating to the pcre library? It seems to have a lot of neat features, and also
hasa jit, and it looks like it is being actively maintained and has decent comments.<br /><br /><br /><div
