Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


When I want to check why a given character in a given buffer looks and
acts the way it does, I like to use M-x list-text-properties.  What I
like about it is the list of all text-properties used and their
values.  Now if the information I want is in overlays, I cannot get to
it.  I must use M-: (setq o (overlays-at (point))) switch to the
scratch buffer and test some of the properties myself explicitly,
there is no way to "just list" them.

There is an interesting function get-char-property, but that, too,
requires me to give the property.  I would like something like M-x
list-char-properties-at (with all the properties in effect at t, and
list-overlay-properties-at (with a section for every overlay at point
and every property in those overlays as structured as with
list-text-properties-at).

Alex.
