Oh gross.  I hate when the alphabetical thing creeps into style guides.  I find it really discriminatory towards non-native English speakers.  Since it is part of the style guide, I think that we should roll with it.  However, if it is ever the case that a non-native English speaker PRs code with includes in the wrong order, the onus is on us the native speakers, not them, to fix it. We should not deny a PR in this situation.  

At least they got the grouping of includes right.
