2019-03-26 regex cleanup
Problems reported by Mattias Engdegård in: https://lists.gnu.org/r/emacs-devel/2019-03/msg01028.html * lisp/align.el (align-rules-list): * lisp/speedbar.el (speedbar-check-read-only, speedbar-check-vc): * lisp/vc/diff-mode.el (diff-add-change-log-entries-other-window): * lisp/woman.el (woman-parse-numeric-arg): Put "-" at end of character alternatives, since a range was not intended. * lisp/erc/erc.el (font-lock): * lisp/mail/footnote.el (cl-seq): Avoid duplicate character alternatives by using cl-seq API. * lisp/mail/footnote.el (footnote--current-regexp): * lisp/textmodes/css-mode.el (css--font-lock-keywords): Avoid repetition of repetition. * lisp/net/webjump.el (webjump-url-encode): Add ~ to character alternatives, and rewrite confusing range. * lisp/progmodes/verilog-mode.el (verilog-compiler-directives) (verilog-assignment-operator-re): Remove duplicate. * lisp/progmodes/verilog-mode.el (verilog-preprocessor-re): * lisp/textmodes/css-mode.el (css--font-lock-keywords): Don’t escape a char that doesn’t need it. * lisp/textmodes/picture.el (picture-tab-chars): In docstring, do not say regexp characters will be quoted; merely say in another way that the syntax is that of character alternatives. (picture-set-tab-stops, picture-tab-search): Don’t attempt to regexp-quote picture-tab-chars. (picture-tab-search): Quote \ in picture-tab-chars for skip-chars-backwards, which treats \ differently than regexp character alternatives do.
