It appears to be due to tabs versus spaces.

None of them appear to be a real issue but it is trivial to make the
warnings go away.

Same ones as #2413, with a couple of extra commits ported forward from older branches since it appears d3b1ce0 overrode the fixes from 9db27f3 and 6529008 in 2d806f1. I will look into submitting these upstream so you don't have to worry about constantly carrying them forward.
