Subject: [net-next PATCH v2 04/14] scripts: kernel-doc: fix parsing function-like typedefs (again)

Typedefs like

    typedef struct phylink_pcs *(*pcs_xlate_t)(const u64 *args);

have a typedef_type that ends with a * and therefore has no word
boundary. Add an extra clause for the final group of the typedef_type so
we only require a word boundary if we match a word.
