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.
