uhmmmmm... yeah, I forgot about that... I've been meddling with the
mod_rewrite regexes lately and haven't used the PHP sort for a
while... I forgot about PHP string escaping

I once ran into trouble with that and could not get the escaping to
work properly, so I just gave up and used {}...

it's the variations that piss me off... the difference between Windows
and Linux implementations of regex libraries for apache (mod_rewrite)
come to mind... 4am on a sunday (well, that's technically monday) also
come to mind... and lots and lots and lots of coke... and waking up 5
