I think I agree.  Both values might be the optimum in different cases.
But most users are probably never interested in shared structures, some
will even be confused.  And those that are interested also know how to
print using print-circle enabled themselves.

Stefan, would it be ok to turn off `print-circle' for
`describe-variable' again, or would this break something in the new
code?

Michael.
