apply: handle "traditional" creation/deletion diff correctly.

Browse source 
We deduced a GNU diff output that does not use /dev/null convention
as creation (deletion) diff correctly by looking at the lack of context
and deleted lines (added lines), but forgot to reset the new (old) name
field properly.

This was a regression when we added a workaround for --unified=0 insanity.
