Subject: [PATCH] Remove support for supertabular from RefTeX

* doc/misc/reftex.texi (Builtin Label Environments):
* lisp/textmodes/reftex-vars.el (reftex-label-alist-builtin)
(reftex-default-label-alist-entries): Delete entries for the
supertabular environment.  supertabular is an extension of the
normal tabular environment, and therefore doesn't contain a
caption and label.  Hence, supporting supertabular in RefTeX is
useless.

(cherry picked from commit b71225ed90ab28ad88c22f8fcd1b87c5681eb0a7)
