[PATCH] Test for files with ls

[Lampersperger Andreas]

Hi,

I have there a small patch to commands/ls.c, whichs makes the
ls-command return an error for non existing fils (as the bash ls
command).

With this patch, one can have in the grub.cfg files statements like:

if ls /boot/grub/grub.cfg.gfx ; then
    source /boot/grub/grub.cfg.gfx
fi

I would be glad if you accept the patch or give me comments to improve
the patch.

Andreas
