Ehh, I did not mean "the current behaviour with -W that shows
is_empty_rec makes sense".  The observation you made (which lead to
the conclusion in your next paragraph that it is not a good idea
to show is_empty_rec on the hunk header line) made sense to me.

But I do not think any change from the current behaviour should be
made if -U<n> wins -W (i.e. the first precontext line shown in the
hunk header is not due to -W).  We should hunt for the name of the
function whose latter half we are seeing at the beginning of the
hunk in that case.

Thanks.
