Actually, I think you're right. I'll have to take another look at it. I haven't paid any attention to this for some time, and pretty much forgot all about it until now.

Thanks for the reminder, and pointing out the (new?) problem. As I said, I'll have a look.

EDIT: Okay, now I'm really confused. That regex will fix the input for what's to be substituted, so that you can just delete any instances of two linebreaks (for instance), but won't properly handle the substition if you've got escape characters on the -s argument.

Yeah, I don't know what it's doing.
