traceback using "sop zone"

[Elaine Meng]

Maybe this is premature... just happened to notice there was a "sop zone" command and tried it:

open 4hhb
surf
sop zone #1.1 near /a:hem range 5 max 2

which seemed to work but gave traceback:
Traceback (most recent call last):

The max_components option of sop zone is not yet working.
