So there's precedent, but precedent alone isn't a very strong argument here.
If people are used to always providing a moveto as the first path component,
they can continue to do that with Jonathan's proposal and everything will
work.

A well-designed language minimizes the amount of RTFMing.

AFAIK the only significant argument against changing this is that it
introduces potential interop problems with existing UAs for only a small
gain. But the next time we extend path syntax, I think we should definitely
start allowing non-movetos as the first component.
