I've commited the first two hunks of this patch to the maint branch,
and fixed up a missing hyphen:

>  print_usage:
> -	fprintf(stderr, "%s: Usage: open [-s superblock] [-b blocksize] [-c] "
> +	fprintf(stderr, "%s: Usage: open [-s superblock] [-b blocksize] "
> +		"[d image_filename] [-c] [-i] [-f] [-e] [-D] "


I'll add the final commit to the master/next branch, which is where
the ls -c option was added without updating the usage message.
