The Elisp manual says of the overlay evaporate property:
`evaporate'
If this property is non-`nil', the overlay is deleted automatically
if it becomes empty (i.e., if its length becomes zero). However,
if the overlay is _already_ empty, `evaporate' does not delete it.
Foverlay_put has explicit code to delete an empty overlay
if you give it a non-nil evaporate property. It has been there
for 10 years. So I'll change the manual.
Thanks.
