That's your personal preference wrt how much of the context should be
left on the screen; it is well known that there are other preferences
regarding this aspect.  Gregory's code provides the default Emacs
experience of recentering, so it is the right default.  If we want to
cater to other preferences, we need to make the 1st argument to
recenter depend on scroll-related options, or maybe introduce a new
user option.
