* mail/rmail.el (rmail-show-message-1): When displaying a mime message,

       indicate start and finish in the echo area.

       * mail/rmail.el (rmail-epa-decrypt): Disregard <pre> before armor.
       Ignore more kinds of whitespace in mime headers.
       Modify the decrypted mime part's mime type so it will be displayed
       by default when visiting this message again.

       * net/browse-url.el (browse-url-firefox-program): Prefer IceCat, doc.
       (browse-url-firefox-arguments)
       (browse-url-firefox-startup-arguments): Doc fix.
