        * glist.c: minor optimizations:
        (g_list_append): `if' optimized for common code path, commented out
        unneccessary `assert', saved one variable assignment.
        (g_list_prepend): saved two (conditioned) variable assignment.
        (g_list_insert): saved one  (conditioned) variable assignment,
        saved one variable assignment.
        (g_list_remove): `if' optimized for common code path, saved two
        variable assignments by using `g_list_free_1' (which is even
        faster) instead of `g_list_free'.
        (g_list_reverse): saved allocation of one variable, saved one
        variable assignment.
