Try using the user-defined widget copy-earlier-word --- it still starts
by copying the immediately preceeding word chunk, but you can repeat it
to copy what's before that.  So you just need to type ^O twice.

It's an interesting (but not *that* interesting) student excercise to
make a widget to do exactly what (I think) you want:  test if there's
white space before the cursor, if so call copy-earlier-word once, else
call it twice.  For bonus points (now this is getting a bit
interesting) check if the whitespace might be part of an uncompleted
quoted argument.

(Second time in a week I've found myself getting confused between "word"
and "argument"...)
