[PENNMUSH] Preserving % at input

[Talvo Hornblower]

Hi Jason,

You're right, having checked it it doesn't work as-is. Testing briefly on PennMUSH 1.8.0p1, though, it looks like this will work. 
(You'll need to totally erase your 'http*' command, and replace #12345 below with the right dbref.)

@hook/ignore huh_command=#12345,check_url
&check_url #12345=switch(%c,http://*,nsremit(%L,%n \(%#\) enters the URL: %c)0,1)

I'm not sure if that's really proper use of HUH_COMMAND, but it does seem to work.

Mike
