Change all regexps to use things like \_< and \_>. * lisp/progmodes/ada-mode.el (ada-mode-abbrev-table): Consolidate declaration. (ada-mode-syntax-table, ada-mode-symbol-syntax-table): Initialize in the declaration. (ada-create-syntax-table): Remove. (ada-capitalize-word): Don't mess with the syntax of "_" since it already has the right syntax nowadays. (ada-goto-next-word): Don't change the syntax of "_". * lisp/progmodes/autoconf.el (autoconf-definition-regexp) (autoconf-font-lock-keywords, autoconf-current-defun-function): Handle a _ with symbol syntax. (autoconf-mode): Don't change the syntax-table for imenu and font-lock. * lisp/progmodes/vera-mode.el (vera-underscore-is-part-of-word): * lisp/progmodes/prolog.el (prolog-underscore-wordchar-flag) (prolog-char-quote-workaround): * lisp/progmodes/cperl-mode.el (cperl-under-as-char): * lisp/progmodes/vhdl-mode.el (vhdl-underscore-is-part-of-word): Mark as obsolete. (vhdl-mode-syntax-table, vhdl-mode-ext-syntax-table): Initialize in their declaration. (vhdl-mode-syntax-table-init): Remove. * lisp/progmodes/ld-script.el (ld-script-mode-syntax-table): Use symbol syntax for "_". (ld-script-font-lock-keywords): Change regexps to use things like \_< and \_>. * lisp/progmodes/m4-mode.el (m4-mode-syntax-table): Add comment on last change. * lisp/font-lock.el (lisp-font-lock-keywords-2): Don't highlight obsolete with-wrapper-hook. * lisp/mh-e/mh-comp.el (mh-regexp-in-field-p): Minor simplification.

;;; Commentary:
|
|
|
|
;; A smart editing mode for m4 macro definitions. It seems to have most of the
|
|
;; syntax right (sexp motion commands work, but function motion commands don't).
|
|
;; It also sets the font-lock syntax stuff for colorization
|
|
|
|
;; To Do's:
|
|
|
|
;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ?
|
|
;; * sexp motion commands don't seem to work right
