[PATCH v4 0/6] More ls improvements

[Glenn Washburn <development@efficientek.com>]

Considering Daniel's feedback on the v2 of this patch series, I've broken up
patches #1 and #2 and dropped patch #3 from the original series. These changes
make the output of the ls command a little more like the GNU ls output.

v4: Add missing parenthesis

Glenn Washburn (6):
  commands/ls: Return proper GRUB_ERR_* for functions returning type
    grub_err_t
  commands/ls: Merge print_files_long and print_files into print_file
  commands/ls: Show modification time for file paths
  commands/ls: Output path for single file arguments given with path
  commands/ls: Print full paths for file args
  commands/ls: Add directory header for dir args
