Heh. Actually I completely missed it.

This brings up an interesting point. "emerge --world" really should fail as
not being valid as it is not an action but a target. With the goal of having
targets user configurable, treating them as options really doesn't work.

So, I'm also moving toward just printing warnings for the time being.
However, we should probably figure out exactly how it should work and then
print warnings whenever any deprecated syntax is used. Not so much for users
and scripts, of which I can't see there being much of a problem, but so that
we can redo that whole bunch of code without having to do:

if incorrect_syntax:
    print warning
    make correct syntax
