environment script: XMODIFIERS

[techgtf]

I was checking out the environment variables on my system (Knoppix 3.2 hdinstall), and it ends with the variable XMODIFIERS and the value for that is a long script (must be over a thousand lines, since it can't all fit in Konsole without using less at my current line limit) that starts like this:

ofl.ini
_alias ()
{
    local cur;
    COMPREPLY=();
    cur=${COMP_WORDS[$COMP_CWORD]};
    case "$COMP_LINE" in
        *[^=])
            COMPREPLY=($( compgen -A alias -S '=' -- $cur ))
        ;;

I haven't seen anything like this script as an environ variable in any other distro I've used, and I don't know enough about scripting to figure it out. Does anyone recognize this or know what it's for?

Thanks in advance.
