Hi,
I would like to disallow the use of spaces in filenames (I'd like to do this
in the entire world, but for now just doing it on my system will do :) 

Is there a simple way (even if it means messing with the source a bit) to get
httrack to change spaces to underscores in the files it creates? Presumably it
already has a mechanism to replace characters that are not allowed on the
filesystem - might be useful if this list were configurable?
Cheers,
Ben
