[Rd] new.env does not recognize parents from subclasses of "environment"

[John Chambers]

  Thanks for the report.  Should now be fixed in r-devel and 2.12 
patched (rev 53383).

Please do report any cases where a subclass of environment doesn't 
work.  There are some known cases in locking and active binding, that 
will be fixed in due course.

The workaround for any such problem is usually as.environment().
