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.
