Change C tabs to spaces w/ clang-format?

[James Browning]

I have had a merge request !1435[1] where I add config files for automatic file styling, error checking, and spell checking. I requested feedback here previously[2],

To the point I would like comments on replacing leading tabs in C with groups of 4 spaces sort of like PEP7[3]. Please comment even if your stance is apathy or indifference.
