Omit/rewrite useless regexp repetitions
Problem reported by Mattias EngdegÄrd in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00527.html * lisp/align.el (align-rules-list): * lisp/cedet/srecode/srt-mode.el (srecode-font-lock-keywords): * lisp/emacs-lisp/copyright.el (copyright-regexp): * lisp/erc/erc-backend.el (JOIN): * lisp/erc/erc-goodies.el (erc-unmorse): * lisp/mail/mail-extr.el (mail-extr-telephone-extension-pattern): * lisp/net/tramp-adb.el (tramp-adb-prompt): * lisp/org/org-table.el (org-table-range-regexp): * lisp/progmodes/idlwave.el (idlwave-where): * lisp/progmodes/verilog-mode.el (verilog-declaration-re-2-no-macro) (verilog-declaration-re-2-macro, verilog-delete-auto-buffer) (verilog-auto-inst-port): * lisp/url/url-misc.el (url-data): Omit or rewrite useless repetitions that risk being very slow in the backtracking regexp engine in Emacs.
