98 * M and m, 2^10 for K and k
99 * 'T' double
100 * user mode accepts an optional ms, us, ns suffix,
101 * which divides the value by 1e3, 1e6, 1e9, respectively
102 * '/' optional gdb-like print format (like "/10x")

104 * '?' optional type (for all types, except '/')
105 * '.' other form of optional type (for 'i' and 'l')
