Here's one improvement for resiliency. Change:

 (if (= 1 (length new-prop))

to:

 (if (>= 1 (length new-prop))

This will catch what is *supposed* to be the impossible case of '(), ie.
at the entry to the function the face property was malformed as a single
item list and had its single element removed.
