[isabelle-dev] Auxiliary contexts again

[Makarius]

Here are some leftovers from the last release concerning the nested 
auxiliary contexts:

The first three are should somehow work in Isabelle/18cb42182d3e, the 
others are still unclear.  Are there further issues still pending?


This is all from our National Debts department in some sense, and should 
at least become a bit better with every release.
