xdiff: -W: don't include common trailing empty lines in context
Empty lines between functions are shown by diff -W, as it considers them to be part of the function preceding them. They are not interesting in most languages. The previous patch stopped showing them in the special case of a function added at the end of a file. Stop extending context to those empty lines by skipping back over them from the start of the next function.
