fix matching regexp for :name* patterns

[wanderview]

We have found a bug in both upstream path-to-regexp and the chromium implementation. We will need to update the spec to fix this bug as well.

I can provision the suggested fix to path-to-regexp and chromium, adding tests so we could catch any regressions. Would this be okay with you?

I already have a fix written for chrome at:

https://chromium-review.googlesource.com/c/chromium/src/+/3123654

If you want to make a PR for pillarjs/path-to-regexp#260, though, that would be great. I think the offending line of code is:

https://github.com/pillarjs/path-to-regexp/blob/master/src/index.ts#L566

@wanderview, yeah, saw your fix.

Sure, I'll open a pull request to path-to-regexp and ensure it's covered there. Should address this today-tomorrow.
