bug#5349: 23.1; [dired] can't enter directories whose name starts with space

[David Abrahams]

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 bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

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

Create a directory "foo" containing another directory named " bar".
Visit foo, position point on " bar", hit return.  I get a "File no
longer exists" error.

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
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.

Hmm, I can't reproduce this on i686-pc-linux-gnu, using either 23.1 or
the latest bzr version.  This may be specific to Mac OS X somehow.
