I believe that the behavior should again depend on the insertion-type
of the overlay's boundary.  If point is just at the beginning of an
overlay with a before-string and inserting a char will move the
overlay's boundary, then the cursor should be displayed before
the before-string.
This was recently brought up when discussing code that adds a "¶" at
end of paragraphs (using a before-string property): the current code
always displays the cursor just after this string, which looks very odd
since typed text will be inserted before the string.
