for the case that the column in the directory listing is too short. This had been disabled since 1994, for no obvious reason and without any comment. * src/screen.c (format_device_number): Added. Converts a device number into a bounded string. * screen.c (string_file_size): Support for larger device numbers (and for non-Linux systems). * vfs/cpio.c (cpio_read_crc_head): Fixed device number handling for non-Linux systems. * vfs/fish.c (fish_dir_load): Likewise. * vfs/utilvfs.c (vfs_parse_ls_lga): Likewise.
