bug#24378: [PATCH 5/6] Don’t allocate char-table’s extra slots in regexp-out-charset

[Michal Nazarewicz <mina86@mina86.com>]

* lisp/emacs-lisp/regexp-opt.el (regexp-opt-charset): Do not use
'case-table as charmap char-table’s property.  The function has nothing
to do with casing and in addition using 'case-table causes unnecessary
extra slots to be allocated which ‘regexp-opt-charset’ does not use.
