Possibly expand the variable name's embedded variables before using it, as
seen (somewhat) in NetBSD.  This catches a few extra recursion cases that
could be hidden by expanding a NIL variable causing an existing variable to
be returned (which caused infinite looping and climbing memory usage in at
least one case).

Obtained from: NetBSD (in principle)
