Hello all,

   I have written a world wide web browser in emacs lisp, with support
for graphics/zones/etc/etc/ in epoch/lucid/fsf19.  I've run into a
slight problem in epoch 4.x

   To keep track of where hyperlinks are in a buffer, and where they
point, I set the data field of a zone.  The problem arises when text
is inserted at the beginning/end of the zone - the text is
automatically included in the zone.  This is a Bad Thing.

   I have implemented the HTML+ forms, and rely on having accurate
start/end points of the zones for removing the old information in the
buffer and inserting the newly entered data.  The document will look
like this:

   * [ ] Check box #1
   * [ ] Check box #2
   * [X] Check box #3

^^^^^^^^ this whole area of text is in the zone that says 'this is a
form entry area'.  When the user clicks in the checkbox, it deletes
the entire zone, including the ' * '.  When I re-insert the [X] or [ ]
to indicate a checked/unchecked box, the formatting is totally hosed.
I got around this in emacs 19 and lucid emacs 19.x by setting the
extent/text properties 'start-open and 'end-open, and it works fine.
Also got around this problem in emacs 18 by using
insert-before-markers.

   Is there anything similar to insert-before-markers for epoch?  Or a
way to tell it to not add new text to a zone?

   Thanks for any information,
	Bill P.
