The problem is that built-in variables like this don't become normal
user variables when the assignment happens.  I don't see a simple fix
for this problem, because some built-in variables should remain
special evan after assignment.

I don't think I'll be able to fix this for 2.0.6, but I'll try to do
it for 2.1.
