OK, you are right, but:
Hmmm.. I am not sure what map-extents should here either. Can we
have
zero length extents? I will have to think about.
The change which allows to have zero length text properties doesn't
affect on the extents semantics.
For my justification, (lispref)Text Properties said that:
