Keeping small things simple is half the reason for doing this - it's not
just bisection, it's also the fact that it's much easier to read and
understand a small patch that does one thing than it is to do the same
with a large patch which makes several unrelated changes.  When several
changes are lumped in together it's harder to see the complete version
of any one change in isolation and more effort is required to work out
which goals are being accomplished with any given chunk of the patch.
