Thanks for your suggestion. It seems good to me. I'd push the attached
commit unless someone else objects.

(I presume this change doesn't need copyright assignment form because
most of it is indent adaptation and the substantial change is just
addition of
----------------------------------------------------------------------
    (if (eq computed 'abort)
        (progn (delete-overlay ov)
               t ; so that `TeX-fold-dwim' "gives up"
               )
----------------------------------------------------------------------
. But this may be a border case. Is there anyone who think it needs
copyright assignment?)
