68
 * 'B'          block device name
69
 * 's'          string (accept optional quote)

71
 * 'l'          target long (32 or 64 bit)
72
 * 'M'          just like 'l', except in user mode the value is
73
 *              multiplied by 2^20 (think Mebibyte)
74
 * 'b'          double
75
 *              user mode accepts an optional G, g, M, m, K, k suffix,
76
 *              which multiplies the value by 2^30 for suffixes G and
77
 *              g, 2^20 for M and m, 2^10 for K and k
78
 * 'T'          double
79
 *              user mode accepts an optional ms, us, ns suffix,
80
 *              which divides the value by 1e3, 1e6, 1e9, respectively
81
 * '/'          optional gdb-like print format (like "/10x")
82
 *
83
 * '?'          optional type (for all types, except '/')
84
