Comment 1:

There's a spurious angle bracket inside the first element of htmlstr, but I don't think
it's the issue.

Labels changed: added priority-go1, go1-must, removed priority-triage.

Comment 2:

Shorter example:
package main
import (
    "log"
    "net/url"
    "html/template"
    "os"
)
func main() {
        u, _ := url.Parse("test/")
        if err := template.Must(template.New("x").Parse("{{.}}\n")).Execute(os.Stdout, u); err != nil {
        log.Fatal(err)
    }
}
prints
{  <nil>  test/  }
should print
test/
It is, for some reason, not calling u's String method.

Comment 4:

This is something unique to html/template; changing the import to text/template in rsc's
example results in the expected output.

Comment 5:

That may be why the subject is "html/template: ..." :)
