Mail mode vs message mode |

If we are to switch to message-mode for Emacs 23.2, there remains
several issues that need to be resolved. However, no one has done
anything. If no one has fixed these issues during the next few weeks, I
think we should revert back to mail-mode.
I've taken a quick look, and the problems mainly come in three
categories.
1. Variables that are straightfowardly duplicated by message-mode.
These variables should be either made into variable aliases (assuming
no one would ever want to have different behaviors between
message-mode and mail-mode):
mail-from-style message-from-style
mail-envelope-from message-envelope-from
mail-interactive message-interactive
mail-yank-prefix message-yank-prefix
mail-signature message-signature
mail-signature-file message-signature-file
mail-default-headers message-default-headers
mail-indentation-spaces message-indentation-spaces
mail-mailer-swallows-blank-line message-mailer-swallows-blank-line
This will probably require compatibility code for XEmacs, too.
2. Hook variables. I am not sure what to do about this, but the switch
has bitten at least one use (Bug#3942). Maybe we should make these
variable aliases too:
mail-mode-hook message-mode-hook
mail-citation-hook message-citation-hook
mail-setup-hook message-setup-hook
mail-send-hook message-send-hook
3. Variables that affect mail-mode but have no counterpart in message
mode. These need code changes:
mail-specify-envelope-from <???> message-sendmail-envelope-from
mail-self-blind
mail-yank-ignored-headers
mail-archive-file-name
mail-default-reply-to
mail-default-directory
mail-bury-selects-summary
