    In the last entry you probably mean

             All before-strings from overlays whose beginning-markers do
             advance, and text properties that are not front-sticky,

Yes, thanks.

    As long as there are no empty overlays: Consider two non-empty overlays
    with the same start and end position.  One has a before-string the other
    an after-string.

This scenario is not fully specified.  Please specify, for each
overlay, whether its beginning marker advances and whether its end
marker advances.  If you describe a fully-specified scenario,
I presume I can follow it.

    But I also fail to understand why you included text properties in the
    discrimination.  before- and after-strings are overlay properties,
    stickyness is a text property.

I forgot that before-string and after-string could not be text
properties too.
