x/tools/cmd/goimports: mishandles named imports used under original name

[josharian]

http://play.golang.org/p/gmQEUKYxrG

package main

import (
    "fmt"
    t "time"
)

func main() {
    fmt.Println("Hello, playground")
    time.Sleep(time.Second)
}

Run through imports, results in:

package main

import "fmt"

func main() {
    fmt.Println("Hello, playground")
    time.Sleep(time.Second)
}

Note that the named time import has been removed but not reinserted without the name. The resulting code does not compile. Running through goimports again fixes things.

Low priority corner case.

Seems like a duplicate of #8149, no?

Yeah, looks like it.
