patch: make '-V none' work in the expected way

Internally the code confuses the concept of "the user doesn't want
a backup file" and "the user hasn't defined a type of backup file".

Introduce a new "undefined" backup type to serve the purpose "none"
previously did, and make "none" not generate backup files, as expected.
