bb_getopt_ulflags's return value will be as if "-a -b -c" were
found.
"ww" Option have int counter usaging. For example ps applet:
if w is given once, GNU ps sets the width to 132,
if w is given more than once, it is "unlimited"
int w_counter = 0;
bb_opt_complementally = "ww";
flags = bb_getopt_ulflags(argc, argv, "w", &w_counter);
if((flags & 1))
width = (w_counter == 1) ? 132 : INT_MAX;
else
get_terminal_width(...&width...);
w_counter - have counter -w usaging, must set int pointer
to bb_getopt_ulflags() after all other requires
Special characters:
"-" A dash between two options causes the second of the two
