bug#2228: 23.0.90; rmail-cease-edit ignores changes to the message headers

[Eli Zaretskii]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

If one invokes rmail-edit, and edits the headers of the message, the
changes to the headers are not copied back to the original message
held in rmail-buffer.  The effect is that your edits of the headers
are lost after you type "C-c C-c" to exit rmail-edit.

Note that fixing this properly should not just copy the modified
headers, but also take the necessary actions for special headers like
Content-Type and Content-Transfer-Encoding.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
d:/gnu/emacs/etc/DEBUG for instructions.
