Yes! My point exactly. It's inconsistent!

  Spaces before filename: counted only when escaped
  Spaces after filename: counted even when they're not escaped

This small change leads us to a saner world where spaces on both sides
of the filename are only counted when escaped. And that is good
because this escaping is useful only in those rare, unsettling cases
when a filename must begin or end with spaces.
