[PENNMUSH] Preserving % at input

[Jason Newquist]

Greetings!

We've had a nagging problem on my social MUSH for a while now, and I 
thought I might present it here to see if anyone can help crack it.

We have some code which allows people to simply paste a URL into the 
MUSH, thus:

 	&WWW3_CMD Globals = $http*:  @tr me/url_code =
 		http%0, %N, %#

&url_code then takes these arguments, adds the link to a log, and 
presents the output to everyone in the room.  Kinda nice.  We use it 
a great deal.

However, many URLs contain percent signs (%20 for space being 
infamous, and other special cases abound), and this causes our code 
above some trouble.  According to DEBUG output, the percent signs 
are gone by the time we send %0 as an argument to url_code -- the 
very first time we reference it.

Is there anything we can do to preserve percentages given at input 
time, before they're evaluated and thus vanish?
