I'm looking at some shell scripts a co-worker wrote and there is a line that looks like this:

I can't figure out why any regular expression would need that many backslashes. Can any of you?
Hmmm... perhaps it is a self-referential script? :-P

Yeah, or a self-self-referential script. It'll be 3 more iterations before that single quote at the end gets un-escaped again. Maybe it's using that string to form some SQL insert statement, which might be retrieved later into some other kind of script which outputs some dynamic javascript or something. Whoa I'm getting dizzy.
