Certain file contents break the :r function in Vip

[Wojciech Gac]

Hi everyone!

I've noticed this when messing around with my .emacs file. When you have a
file with a null character somewhere within a double-quoted string
(e.g. "\0") and you try to insert it into the current buffer with :r, then
it breaks Vip with the following message:

 !? (set C T)
                                                NIL -- Protected symbol
                                                                       ?

Any ideas or comments?

Cheers,
Wojtek
