prefix and static file serving interact badly

[adwhit]

Take the following app:

App::new()
    .prefix("/public")
    .handler("/", fs::StaticFiles::new("some/folder")
             .index_file("index.html"));

Test with httpie:

➜  ~ http :8000/public/
HTTP/1.1 302 Found
location: /public/index.html

➜  ~ http :8000/public 
HTTP/1.1 302 Found
location: /publicindex.html

The second test generates an incorrect redirect.

I think the prefix is actually irrelevant. I get the same error with

App::new()
    .handler("/nested", fs::StaticFiles::new("some/folder")
            .index_file("index.html"))

I also find this slightly surprising

    App::new()
        .handler("nested", fs::StaticFiles::new("some/folder")
                 .index_file("index.html"))

➜  ~ http :8000/nested
HTTP/1.1 404 Not Found

In general I would not expect the forward slashes either before or after the prefix or the handler route to affect the routing. But this may be expected behavior.
