An entry (TEXT . POSITION) represents the deletion of the string TEXT
from (abs POSITION). If POSITION is positive, point was at the front
if it has (or is covered by an extent with) a non-nil `invisible' property.
If the value is a list, a text character is invisible if its `invisible'
property is an element in that list.
-If an element is a cons cell of the form (PROP . ELLIPSIS),
-then characters with property value PROP are invisible,
+If an element is a cons cell of the form (PROPERTY . ELLIPSIS),
+then characters with property value PROPERTY are invisible,
and they have an ellipsis as well if ELLIPSIS is non-nil.
Note that the actual characters used for the ellipsis are controllable
using `invisible-text-glyph', and default to "...".
