bug#17488: 24.3; mail-sendmail-undelimit-header doesn't respect mail-header-separator

[Katsumi Yamaoka]

Hi,

This is probably a rare case, so I'm not sure if it's worth
fixing, though.  If one sets `mail-header-separator' to

"                                       ."

it causes a mail corruption.  It is because `rfc822-goto-eoh'
doesn't respect `mail-header-separator' and the first line of
a message body, rather than the separator, is deleted.

`smtpmail-send-it' and `mailclient-send-it' use it by way of
`mail-sendmail-undelimit-header'.  And `sendmail-send-it' uses
it by way of `mail-header-end'.

Thanks.

Hm...  I think `rfc822-goto-eoh' does the right thing: It doesn't care
about `mail-header-separator', because that's a user setting for mail
composition buffers, not something that should be consulted after making
that buffer into an RFC2822 mail.

So `mail-sendmail-undelimit-header' should consult that variable, I
think, instead of using `rfc822-goto-eoh'?

I see.  It got obvious that `rfc822-goto-eoh' shouldn't respect
`mail-header-separator' after having understood what
`mail-sendmail-delimit-header' does --- it looks for *eoh* using
`rfc822-goto-eoh' and then inserts `mail-header-separator'.  So,
it's a function that converts an RFC2822 mail into the one usable
in a mail composition buffer.  Although there is no program that
uses `mail-sendmail-delimit-header' in Emacs.

I think it will work, but I changed my mind.  That is,
`rfc822-goto-eoh' should be used with an RFC2822 mail, and a mail
composing software should replace the `mail-header-separator' with
an empty line before sending a mail to the `sendmail-function',
like Gnus does.

Yes, they should, so `mail-sendmail-undelimit-header' will normally be a
function that does absolutely nothing (as it is today :-)).  So it
should either be removed, or adjusted to do what it says it does (i.e.,
find the delimited and remove it).  I'll do the latter, and we can
contemplate the former...

This change caused the following error:

Debugger entered--Lisp error: (search-failed "^--text follows this line--\n")
  re-search-forward("^--text follows this line--\n")
  mail-sendmail-undelimit-header()
  smtpmail-send-it()
  message-smtpmail-send-it()

So, I've added ``nil t'' to the re-search form.  ;-)
