Description

I have template directory with only one file:

But LoadHTMLGlob found extra template without a name

How to reproduce

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    router := gin.Default()
    router.LoadHTMLGlob("templates/*")
}

Expectations

[GIN-debug] Loaded HTML Templates (1): 
    - index.tmpl

Actual result

[GIN-debug] Loaded HTML Templates (2): 
    - 
    - index.tmpl

Environment

• go version: 1.16.3
• gin version (or commit ref): I ran today go get -u github.com/gin-gonic/gin. Nowhere was it written which version was installed.
• operating system: WIndows 10

~I believe it should be some issues in matching template files, then the default template name set by templ := template.Must(template.New("").Delims(left, right).Funcs(engine.FuncMap).ParseGlob(pattern)) is used.~ Edit: The empty template without name is caused by template.New("").

Ha ha, so it is. It's hard for those who pursue perfection.

I can confirm the behavior and while only confusing, i think that there is a random empty entry in a list is weird behavior for such explicit language as Go, can this be fixed? :)
