After revision 5010, issuing the ls command with a device name as
parameter gives a response such as:
(device_name): Filesystem is <filesystem name>.
But grub.texi says:
"
@deffn Command ls [arg @dots{}]
List devices or files.
With no arguments, print all devices known to GRUB.
If the argument is a device name enclosed in parentheses (@pxref{Device
syntax}), then list all files at the root directory of that device.
If the argument is a directory given as an absolute file name (@pxref{File
name syntax}), then list the contents of that directory.
@end deffn
"
Which is the correct behavior?
