85 * 's' string (accept optional quote)
86 * 'O' option string of the form NAME=VALUE,...

96 * user mode accepts an optional T, t, G, g, M, m, K, k
97 * suffix, which multiplies the value by 2^40 for
98 * suffixes T and t, 2^30 for suffixes G and g, 2^20 for
99 * M and m, 2^10 for K and k
100 * 'T' double
101 * user mode accepts an optional ms, us, ns suffix,
102 * which divides the value by 1e3, 1e6, 1e9, respectively
103 * '/' optional gdb-like print format (like "/10x")
105 * '?' optional type (for all types, except '/')
106 * '.' other form of optional type (for 'i' and 'l')
107 * 'b' boolean
108 * user mode accepts "on" or "off"
109 * '-' optional parameter (eg. '-f')
