bug#2016: 23.0.60; rmail-toggle-header not limited to current 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:

Typing `t' in an Rmail buffer causes all the messages to be displayed
with their full headers.  Before the mbox merge, the effect of `t' was
limited to the single message that was displayed at the time `t' was
pressed, and typing `n' or `'p' to go to a different message would
undo `t'.  If you came to the same message where `t' was used, after
looking at other messages, the effect of `t' was also undone, and you
had to type `t' again to see the full headers.

If this is a deliberate change in behavior, it should be in NEWS.

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.
