Disable staging and unstaging lines or hunks when the diff context size is 0

Browse Source 
Git diff and patch doesn't work reliably with a context size of 0, so disable it
in this case (and discarding changes as well). Magit does the same, see
https://github.com/magit/magit/issues/4222.

Staging entire files by pressing space in the Files panel is still possible, of
course.
