inredir and linredir in get_comp_string() probably have something to do
with this.  It looks like the "word" it thinks it's on is the "1" after
the ">", rather than the "2" before it.

It would probably be sensible to take the attitude that we just shrug
our shoulders until somebody volunteers to rewrite get_comp_string()
properly to use a state machine.

However, sense and completion code maintainance have never had a lot to
do with one another.
