bug#2137: 23.0.60; Saving Rmail buffer does not show the "Saving file ..." message

[Eli Zaretskii <eliz@gnu.org>]

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:

In an Rmail buffer, type "C-x C-s" to save it: you will almost never
see the usual "Saving file FOO..." message, because buffer-soze,
called by save-buffer, returns the size of the current message, not of
the entire message collection.

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.
