+
+Arguments:
+ string points to the start of the string that is being built, or NULL
+ if this is a new string that has no contents yet
+ s points to characters to add
+ count count of characters to add; must not exceed the length of s, if s
+ is a C string.
+
+Returns: pointer to the start of the string, changed if copied for expansion.
+ Note that a NUL is not added, though space is left for one. This is
+ because string_cat() is often called multiple times to build up a
+ string - there's no point adding the NUL till the end.
