Argh!  Vladimir had the same question, I thought I'd put it back.  I have now.
I've also used:
 
  strcmp (var->print_value, print_value) != 0

since that method seems to be the norm in varobj.c, and GDB generally.

I've committed this change, which you might not like, because I think Vladimir
is agreeable to it.  Of course, I'll make changes, including reversion, if
there are problems.
