Forums Bug Reports Problem with masks in $mask $address and /ignore

There is a problem is Problem with masks in $mask $address and /ignore when the user part of the fulladdress is longuer than 10 chars.

Examples:

var %w = nick!verylonguser@hostname
echo $mask(%w,0)
>> *!rylonguser@hostname

echo $mask(%w,1)
>> *!*ylonguser@hostname

echo $mask(%w,5)
>> nick!rylonguser@hostname

I would expect $mask(%w,5) to at least return the correct fulladdress.
