In xchat aqua 0.15.1 with Mac OS X 10.4.4 the autoreplace-function does
notwork properly. Consider you have an entry to replace 'teh' with 'the'.
When you type 'teh' you will see in the channel window 'teh', but other
users in the channel will see the right word 'the'. So the autoreplace
function works for all users on the IRC except me ;o)
