.editorconfig

util: use `iter(callable, sentinel)` instead of while True

This is functionally equivalent, but is a little more concise.

# See http://EditorConfig.org for the specification

root = true

[*.py]
indent_size = 4
indent_style = space
trim_trailing_whitespace = true

[*.{c,h}]
indent_size = 8
indent_style = tab
trim_trailing_whitespace = true
