Double groan - I hit the wrong key (send rather than abort) with a
partially written incorrect message. Drat.

I was fooled as the "Precedes:" entry is blank if I do, for instance:
   git checkout -b foo master~1
   gitk
even though HEAD=foo which precedes master. However, master shows up
in the list of branches containing the commit. So yes, I see that gitk
has the full DAG available and could therefore generate a useful
warning when deleting a branch would leave dangling commits.
