When we see no context nor deleted line in the patch, we used to declare that the patch creates a new file. But some people create an empty file and then apply a patch to it. Similarly, a patch that delete everything is not a deletion patch either. This commit corrects these two issues. Together with the previous commit, it allows a diff between an empty file and a line-ful file to be treated as both creation patch and "add stuff to an existing empty file", depending on the context. A new test t4126 demonstrates the fix. Signed-off-by: Junio C Hamano <gitster@pobox.com>
