No, the `face FACE` *cannot* be omitted: the `face' symbol in the car is
tested to distinguish this case.  Note also that the `PROP1 VAL1 ...`
are *not* face properties, they are *text* properties.

The above docstring should probably replace "face name" by "face" but
other than that it looks about right.
