diff --whitespace=warn/error: fix blank-at-eof check
The "diff --check" logic used to share the same issue as the one fixed for "git apply" earlier in this series, in that a patch that adds new blank lines at end could appear as @@ -l,5 +m,7 @@$ _context$ _context$ -deleted$ +$ +$ +$ _$ _$ where _ stands for SP and $ shows a end-of-line. Instead of looking at each line in the patch in the callback, simply count the blank lines from the end in two versions, and notice the presence of new ones.
