Default variants

[N_Ox]

 From what I've understood, the problem with default variants is that  
if we do something like `port foo -bar` and that foo has  
`default_variants +bar`, if an upgrade of foo is released, then `port  
upgrade foo` will enable bar variant because variant disabling are  
not saved and `default_variants +bar` will be evaluated.

Is this really a problem?
Can't we use the magic of the TCL interpreter and ignore the call to  
default_variants procedure in upgrade variant?

These were my $0.02 for tonight...
...I'll now take my pills and go to bed :p
