Another feature request

One thing that would be a good idea perhaps is a -V option: that is, 
an option that explains all of the optional parts that have been 
compiled into screen.

Examples of this already exist for apache and vim, and perl I think.

Also, since lua scripting is in the wings.... what about making the 
connection to lua "clean" so one could add tcl if they like?  
Somebody will like that :)
