x/tools/cmd/goimports: unused named import is mistaken for unnamed import

[crawshaw]

$ goimports <<EOF
package main

import foo "fmt"

func main() { fmt.Println() }
EOF

Prints:

package main

func main() { fmt.Println() }

Low priority, as a second run corrects the import.

I hit a similar issue today, probably related.
