2 bugs

hi Al.

Savants LANG_GEDA uses get_line on a CS initialized by a (one line)
string. this is not necessary, but i think valid. so get_line must be
extended to throw Exception_End_Of_Input in that case. currently it runs
into assert(_file==stdin) unless _file, which is bad.

when typing
> verilog
> module foo();
> endmodule;
> foo a(1,2);
> list
the 3rd assertion in COMPONENT::port_value(int i)const is hit.
compiled with -DNDEBUG it outputs 
[..]
foo #() a (.?????(1),.?????(2));
so either this is correct, or the instanciation of a should fail.
