Sorry, I didn't explain why I queried this paragraph. To me, "the
patching attempt" began before the callback, which is the main thing I
was clarifying in the first hunk above, so this paragraph is inaccurate.
It is not clear to me whether the client really needs to pay attention
to notifications, or if the callback can just look at whether any
non-empty "reject" file was created, to know whether there was a
problem. If there was no problem at this stage, then the patching is
more or less guaranteed to be successful -- there are very few reasons
why the final "move into place" step might fail.
