The need for relative public path (to the endpoint, not hostname) in the production build

[lexfrl]

User story:
I want to publish my app on, for example, Github Pages and I want to leave PUBLIC_URL as a default due to possibility of change of the endpoint url or share the build between several endpoints.

Thanks for the PR, but AFAIK this breaks file-loader. If you build a project you will see that the image file URLs are broken. That's what the comment above that line says.

We don't officially support reusing the same build on different URLs. It's a limitation caused by how we approach bundling. I think it's best for single page apps: most of them wouldn't work on arbitrary URLs anyway, and this tool is meant for single page apps.

So if you want to serve from multiple URLs you'd need to do multiple builds.
