Ambiguous component name error does not mention first character cannot be numeric.

[ThePendulum]

When assigning a component name, it is matched against a regex that does not allow the first character of the name to be numeric. However, the error thrown only mentions that the component name has to be alphanumeric:

Invalid component name: "0650475a". Component names can only contain alphanumeric characaters and the hyphen.

Other than the typo 'characaters', the provided component name also matches the condition of the error. It would be helpful if ~~~either the regex or~~~ the error is changed accordingly.

Thank you in advance!

The component name can't start with a digit any more than HTML/XML tag names can, simply because the component name '0650475a' will be turned into a tag name <0650475a>.

Oh, I see you've modified the subject. In such a case, maybe a more helpful warning can be introduced.

I understand that, but maybe the error message can highlight this fact?

Heh, let me not edit that last message then since we're on this in real time; that is indeed what I was thinking, thanks! :)

Interestingly your issue just revealed a typo in Vue's source code. I'll see to that too.
