[patch] wide char form_driver

[Gaute Hope]

Greetings,

We recently ran into some issues with form_driver with UTF-8 input on
Mac OS X. We use ncurses for Sup (a ruby mail client).

I have attached a patch with a form_driver implementation that accepts
wide chars and a type (KEY_CODE_YES or OK) as returned by get_wch (). So
we just skip the whole figuring out whether it is a char or not.

A public method, form_driver_w is implemented with a private Data_Entry_w
method to go with it, they are minor modifications from their existing
siblings:


    form_driver_w (FIELD *field, int type, wchar_t c)


A test program is included in test/: form_driver_w.

I know that a lot of users have had problems with form_driver and wide
chars and I hope this is of interest, but it requires more testing and
probably some more thought. Untested with mouse support.
