Thanks. Most of that has already been done now, but I'll certainly
keep your functions handy. I'll likely need them at some point.
One thing you might want to keep in mind is that this little "fix" is
going to get executed on each request if you just throw it in an
include. I ran stripslashes_deep() against my 5.2.1 release and here
are the results:

That means lots function calls happened before you could even say
hello world. You might want to add wrapper functions accessor
functions around $_GET and $_POST so that you're only stripping when
really necessary.
