bug#2022: 23.0.60; Rmail buffer marked modified after saving it

[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:

To reproduce:

  emacs -Q
  C-u M-x rmail FOO RET
  C-u g FOO.2 RET

The last command automatically saves the Rmail inbox (as it should),
but the buffer is nevertheless marked modified after the save.

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.
