ignore hard-tabs in code block

[liyongjing]

for example

func main() {
    r := gin.Default()
    r.GET("/", func(c *gin.Context) {
        c.String(http.StatusOK, "Hello from %v", "Gin")
    })

    r.Run(":3000")
}

In my mind, hard tabs are a problem because no two tools agree on how many spaces they should be. For example here on GitHub, they've converted the tabs in your example to 4 spaces, though it's common to see 8-space or 2-space tabs. Because of this, I consider tabs equally problematic inside code blocks as they are outside and I think this warning is correct to fire inside a code block.

Does that seem reasonable?

@DavidAnson Sorry to bother you. The explanation is very reasonable.
But go recommends tabs instead of spaces. And almost all go projects are using tabs (in 2016).

Waiting for #82 being resolved in the future :-)
