check-commit: allow foo_bar naming in functions

nameswithallthewordssmashedtogetherarehardtoread.
especiallyifenglishisnotyourprimarylanguage.

Let's align with the rest of the programming universe and
allow_the_use_of_underscores_in_names.

We took a hand poll at the 5.2 sprint regarding this change and
all but 1 person supported it. The person who didn't expressed
concerns around excessive API breakage if we mass renamed things.
But we're not planning to mass rename things for the sake of
renaming, so all should be well.
