Function split_string

string-list.c:333–364

* Unfortunately this cannot become a public interface, as _in_place() * wants to have "const char *string" while the other variant wants to * have "char *string" for type safety. * * This accepts "const char *string" to allow both wrappers to use it; * it internally casts away the constness when in_place is true by * taking advantage of strpbrk() that takes a "const char *" arg and * return

 * returns "char *" pointer into that const string.  Yucky but works ;-).
