emacs/lisp/mail/rmail.el
Richard Stallman 4e23cd0ccd * 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.

;;; Commentary:
;;; Code:
;; Souped up by shane@mit-ajax based on ideas of rlk@athena.mit.edu
;; New features include attribute and keyword support, message
;; selection by dispatch table, summary by attributes and keywords,
;; expunging by dispatch table, sticky options for file commands.
;; Extended by Bob Weiner of Motorola
;; New features include: rmail and rmail-summary buffers remain
;; synchronized and key bindings basically operate the same way in both
;; buffers, summary by topic or by regular expression, rmail-reply-prefix
;; variable, and a bury rmail buffer (wipe) command.

marked as `filed', or are in different folders, are left alone.

FOLDERNAME is the name of a folder in which to put the message.
If FOLDERNAME is nil then Rmail deletes the message, and moves on to
the next. If FOLDERNAME is \"/dev/null\", Rmail deletes the message,
but does not move to the next.
FIELD is the name of a header field in the message, such as
\"subject\" or \"from\". A FIELD of \"to\" includes all text
from both the \"to\" and \"cc\" headers.
REGEXP is a regular expression to match (case-sensitively) against
the preceding specified FIELD.
There may be any number of FIELD/REGEXP pairs.
All pairs must match for a directive to apply to a message.
For a given message, Rmail applies only the first matching directive.

(\"RMS\" \"from\" \"rms@\") ; save all mail from RMS.

the Rmail file it is initialized using either
`rmail-primary-inbox-list', or the \"MAIL\" environment variable,
or the function `user-login-name' and the directory
`rmail-spool-directory' (whose value depends on the operating system).
The command `set-rmail-inbox-list' sets `rmail-inbox-list' to the
value you specify.
You can also specify the file to get new mail from just for one
instance of this command. In this case, the file of new mail is
not changed or deleted. Noninteractively, you can pass the inbox
file name as an argument. Interactively, a prefix argument
causes us to read a file name and use that file as the inbox.
If the variable `rmail-preserve-inbox' is non-nil, new mail will
always be left in inbox files rather than deleted.
Before doing anything, this runs `rmail-before-get-new-mail-hook'.
Just before returning, it runs `rmail-after-get-new-mail-hook',

Toggle the display of a MIME message.
The actual behavior depends on the value of `rmail-enable-mime'.
If `rmail-enable-mime' is non-nil (the default), this command toggles
the display of a MIME message between decoded presentation form and
raw data. With optional prefix argument ARG, it toggles the display only
of the MIME entity at point, if there is one. The optional argument
STATE forces a particular display state, rather than toggling.
`raw' forces raw mode, any other non-nil value forces decoded mode.
If `rmail-enable-mime' is nil, this creates a temporary \"*RMAIL*\"
buffer holding a decoded copy of the message. Inline content-types are
handled according to `rmail-mime-media-type-handlers-alist'.
By default, this displays text and multipart messages, and offers to
download attachments as specified by `rmail-mime-attachment-dirs-alist'.
