pgenutil.pas, generate_specialization:
* use "is_generic" instead of "df_generic in defoptions" as nested non generic types will have that flag set as well and thus would be acceptable for the "<...>" notation although no generic version of it exists
ptype.pas, single_type:
* check for nested types after doing a specialization
+ added tests (one for now working case and one for now forbidden case)
