OK, closing.

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

Do C-x C-f f o o RET.  This opens a file called foo.
Now C-x k, to close that buffer.
Now we attempt to open the file again: C-x C-f C-p.
That doesn't work; C-p was intended to get the previous filename
but gives 'beginning of buffer'.  You need to type M-p instead.

However, in GNU bash, the situation is reversed.  To get the previous
command line you have to hit C-p, and M-p just enters a control
sequence.  So there is a user interface inconsistency between
bash and Emacs.

I think the best way to resolve it is to make C-p and C-n work in
the Emacs minibuffer to get the previous and next lines from the
history, just as M-p and M-n do.  Since the minibuffer is almost
always a single line of text, the bindings to previous-line and
next-line aren't helpful in the minibuffer.

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'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.2/etc/DEBUG.
