I agree that it is rather a subjective decision.

If it is truly "some people prefer it one way and some the other", I am
not sure if we should leave it as-is (that is preferring one way). The
middle ground would be to die(). That does not seem super-friendly, but
then we would also die with GIT_SMART_HTTP=foobar, so perhaps it is not
unreasonable to just consider it a syntax error.

I dunno. I can live with leaving it as-is. Certainly the existing
behavior is not what I expected, but it is not like it came up in the
real world (and I would not expect it to do so often). And it is
consistent with the config, which treats:

  bar =

as boolean false. That _also_ seems weird to me, but that is not
something I think we can easily change or outlaw at this point anyway.
