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:

I have the following directories below ~/uni/repos/

  re-group/
  redseeds-main/
  redseeds-uko/

When I do

  C-x C-f ~/uni/repos/re-<TAB>

the completions are shown and point moves before the hyphen.  To
complete to re-group/ I have to move point explicitly to the end using
`C-e' and enter the g followed by an additional <TAB>.

I think it would be very convenient if <TAB> cycled between all possible
completion points, starting with the last position if the current entry
matches the start of an item completely.  So in my example

  C-x C-f ~/uni/repos/re-<TAB>

would pop up the completion list and let point stay at the end.  An
additional <TAB> would move point to before the hyphen.  Another <TAB>
would move it to the end again.

Is that possible?

It's all tested with emacs -Q.

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/23.0.60/etc/DEBUG for instructions.
