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 <at> gnu.org mailing list.

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

When running emacs with an empty command line argument like this:

emacs ''

it won't start and display the following message:

Option `' is ambiguous

This makes it impossible to just call emacs "$*" inside a shell script
(without checking if "$*" is an empty string).

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
/usr/share/emacs/23.0.90/etc/DEBUG for instructions.
