I should have done too. And I also find these precedence rule somehow
puzzling. To me, it's a bug: the rule you give for Host *.gnu.org was
ignored and, even it's documented, it's still a problem.

No one would imagine a 
        export SHELL=/bin/false
that would be override by a previous
        export SHELL=/bin/bash
for instance.
