Re: Should overlays evaporate by default?

    below is an untested patch that sets the evaporate property
    for newly-made overlays.  munge to taste, etc.

This sets the property to t.
That is not what we are looking for now.

The goal now is to *find* possible bugs.
The patch should set the property to something unusual (maybe
`never-set') by default.  When such an overlay becomes empty, there
should be some sort of warning.  That way, people will find code
that perhaps ought to set the evaporate property to something
