I get your point, but for the indentation case in particular you can use `git diff -w` or append `?w=1` to a github PR url.

Except in Python where indentation changes are meaningful.

    def coalesce(*args):
      while args:
        next = args.pop()
        if next is not None:
          return next
      return None

    def coalesce(*args):
      while args:
        next = args.pop()
        if next is not None:
          return next
        return None
