[reveal-mode] Hiding short expressions

[Ralf Angeli]

Hello,

currently I am trying to make use of reveal-mode for hiding and
revealing \footnote{...} expressions in Emacs.  Now the problem is
that visible expressions under the control of reveal-mode only get
hidden if the cursor moves before the beginning of the line with the
expression or past its end.  If you have short expressions within a
line it would be nice if the expression became invisible as soon as
the cursor moves out of it.

Are there any reasons why this is not handled like this in reveal.el
and would it be possible to change it if there aren't any?  (A patch
would be to replace the `save-excursion' statements around line 119 in
reveal.el by the `overlay-start' or `overlay-end' statements already
defined there.)
