[[NBK] G.I. Jerk]

In the README to the last version you say that if someone wants a word added...or MOTD added they should get you to do it for them as it probably wont work if they do it. I had to try it out of curiosity. As a test I figured I'd try filtering both letters A & B hoping a blank (used ascii ALT 255) would appear. (looking for a better way to do my no-chat mod)

{ "a" " " }
{ "b" " " }

In console I did a "say a" and on screen it read GI Jerk: ?

When I did a "say b" it said b.

Why the difference? Why one but not the other? I just want to figure out the quirks of localization.txt as a learning experiance.
