Regex to find repeated words

Even quicker post than the last one.

For some reason, a lot of times I end up writing “the the” and “show show” and the like. I have no idea why this happens, but I usually say it’s because I’m left-handed and my hand covers the last word as I’m writing. Of course, this doesn’t make any sense since I’m writing on a keyboard, but you know know…

Anyway, here’s a regular expression to find those repeated words, courtesy of stack overflow.
