Karl Fessel 05f114d0af doc: fix unbalaced grouping
- most were trivial
    - missing group close or open
    - extra space
    - no doxygen comment
- name commad might open an implicit group
    this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
