Re: Patch: gw/urltrans.c

Maybe, but AFAIK this is a perl expression and should be used when 
configured with pcre, not regex...

Of course you can do the "[Aa][Bb][Cc]" trick! That was the reason while 
Alex and I told you that case sensitivity mattered and we were against your 
point about disabling it on the first place...

While this method works fine, it's a lot harder to maintain. Being able to 
use "i" would simplify things imho. Not a show-stopper, but would improve 
things.

A similar issue occurs with latin accents (and also the "ρ" in spanish). You 
usually want to accept accented words as well. Time ago, we solved it by 
using [Aaα] [Eeι] ... [NnΡρ] etc. Of course this wouldn't be solved with the 
"i" switch and would still need the bracket trick to work, but at least it 
would be simpler and more readable than having each and every letter between 
brackets in upper and lower case.
