That's an excellent list of regexes, but I'm a bit torn about whether to recommend using it. One the one hand, regexes are a good and sometimes interesting mental exercise. On the other hand, small little discrepancies can cause you headaches. But no pain, no gain... I guess unlike, say, sorting algorithms, which are fairly straightforward, text matching requirements are fickle enough that fixed lists are less helpful. I'm pretty surprised at that software written just for regexes.
