* Fixes issue with template string not being provided in help text
* Updates background information to provide full URL, including path, to make it clear the source and destination
* Restores some tests
* Removes AllowFunnel in ServeConfig if no proxy exists for that port.

EXAMPLES
- Expose an HTTP server running at 127.0.0.1:3000 in the foreground:
$ tailscale %s 3000
$ tailscale %[1]s 3000
- Expose an HTTP server running at 127.0.0.1:3000 in the background:
$ tailscale %s --bg 3000
- Expose an HTTPS server with a valid certificate at https://localhost:8443
$ tailscale %s https://localhost:8443
$ tailscale %[1]s --bg 3000
- Expose an HTTPS server with invalid or self-signed certificates at https://localhost:8443
$ tailscale %s https+insecure://localhost:8443
