sh: Make getopts memory-safe if with changing arguments. POSIX does not permit to continuing a getopts loop with different arguments. For parsing the positional parameters, we handle this case by resetting the getopts state when the positional parameters are changed in any way (and the getopts state is local to a function). However, in the syntax getopts <optstring> <var> <arg...>, changes could lead to invalid memory access. In the syntax getopts <optstring> <var> <arg...>, store a copy of the arguments and continue to use them until getopts is reset. 2014-10-26 17:50:33 +00:00			`# $FreeBSD$`
