Placing it in next_char_default gives us a regression elsewhere.  I am actually
checking to see if after my patch whether the line above is even needed in
next_char_default.  There are a lot of subtle interactions that go into this
code, so i tread lightly.

I will not close this until I have the initial patch back ported and have done
some more testing and others have had time to do more testing.  If you happen
to find a use case that fails, of course, let me know, and thanks.
