bug#2859: 23.0.91; indent-tabs-mode and cua-rectangle editing when using the tab key

["Stefan Reichör" <stefan@xsteve.at>]

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:

(setq-default indent-tabs-mode nil)
I have set indent-tabs-mode to nil
This setting does not work during indenting with cua rectangle mode
The recent input below shows a test case:
Just go to the beginning of a line, hit C-RET
And hit tab to indent a line

I expect the line to be indented with blanks, but tabs are used here.



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
/opt/rhel4/stow/emacs/share/emacs/23.0.91/etc/DEBUG for instructions.
