Being a little slow on the uptake, I only just figured out why I ended
up with that big of a patch.
When given a building and working source tree, I usually make my commits
such that they are small, self-contained and keep the source tree in a
building and working state.
That is why I usually add changes until it finally builds/works.
However, that is a useless argument here, as the state of the source
tree *before* my change is non-building maybe-working, so if the source
tree does not build *after* my small, self-contained change, my change
has not made it worse and can thusly still be considered good.
Changing my normal modus operandi accordingly; considering failing
builds as normal for now.
Expect a good dozen patches in a day or two.
