Summary: Can't expose file command in safe interp

Initial Comment:
Using ActiveTcl 8.6b5 on Ubuntu Linux

I'm having the following problem: 
% set i [interp create -safe] 
interp0 
% interp expose $i file 
::tcl::mathfunc::maxunknown hidden command "file" 
%

Message:
I've made [file] be hidden in safe interpreters, but I don't think it's a
very good idea all the same. The change to having it be an ensemble changes
the way you are best advised to write a security policy (i.e., [file]
should be there, but only with safe operations in it).

Message:
[file] is exposed, but its unsafe subcommands fail.
