Store the pointer to the string allocated by shorten_unambiguous_ref in a dedicated variable, short_base, and keep base unchanged. A non-const variable is more appropriate for such an object. It avoids having to cast const away on free and stops redefining the meaning of base, making the code slightly clearer.
