Empty catch-all routes don't cache empty values

[azavorotnii]

I am trying to use *path catch-all syntax to match both http://localhost:8080/example/some/path and http://localhost:8080/example/. I expect that catch-all syntax will handle latter with empty "path" param, but it doesn't. I got 404.

package main

import (
	"github.com/dimfeld/httptreemux"
	"net/http"
)

func main() {
	router := httptreemux.NewContextMux()
	h := func(w http.ResponseWriter, r *http.Request) {
		params := httptreemux.ContextParams(r.Context())
		w.Write([]byte(params["path"]))
	}
	router.GET("/example/*path", h)
	http.ListenAndServe(":8080", router)
}

I can workaround it with adding one more handler:

	router.GET("/example/*path", h)
	router.GET("/example/", h)

But I didn't have to do it with https://github.com/julienschmidt/httprouter

If this is not an issue by design, I would at least mention this in documentation :)

Yes, this is intentional. I'll add something to the docs soon mentioning it. Thanks!
