Subject: 23.1.50; ido-use-filename-at-point fails for files in default-directory
Date: Thu, 26 Nov 2009 18:29:23 +0100

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.  If you can, give
a recipe starting from `emacs -Q':

Setting ido-use-filename-at-point to 'guess and trying to, for example,
find a included header-file w/o a directory component (#include "foo.h")
fails, because ido thinks that the file is invalid, due to
file-name-directory returning nil.

I think the following patch fixes this.

diff --git a/lisp/ido.el b/lisp/ido.el
