    Mention char classes earlier, in a more-logical place.
    Advise sticking to ASCII letters and digits in ranges.
    Reword negative advice to make it clearer that it’s negative.

    * lisp/gnus/message.el (message-mailer-swallows-blank-line):
    * lisp/gnus/nndoc.el (nndoc-lanl-gov-announce-type-p)
    * lisp/org/org-eshell.el (org-eshell-open):
    * lisp/org/org.el (org-deadline-time-hour-regexp)
    * lisp/progmodes/bat-mode.el (bat-font-lock-keywords):
    * lisp/progmodes/bug-reference.el (bug-reference-bug-regexp):
    * lisp/textmodes/less-css-mode.el (less-css-font-lock-keywords):
    * lisp/vc/vc-cvs.el (vc-cvs-valid-symbolic-tag-name-p):
    * lisp/vc/vc-svn.el (vc-svn-valid-symbolic-tag-name-p):
