Problem with {{{blockcode}}}, moinwiki_in converts it to moin_page:code, equals with `monospace`

Test 8. fails, moinwiki_in does not recognise this input as definition list.

In Test 9. first list item is ' '. We need some changes in moinwiki_in.

For now, moinwiki_out supports definition list, but only one output format:

 this::
 :: A
 :: B
 not_this:: def
