Shell style argument parsing. Handles backslash escaping, single and
double quoted strings but not shell substitutions.
.PP
Pass one or more strings containing shell escaped arguments. The return
value is an array of arguments parsed from the input strings according
to (approximate) shell parsing rules. It's legal to pass \f(CW\*(C`undef\*(C'\fR in
which case an empty array will be returned. That makes it possible to
