1. What did you do?

If possible, provide a recipe for reproducing the error.

jnml@4670:~/src/tmp$ echo $GOPATH 
/home/jnml
jnml@4670:~/src/tmp$ cat tmp.go 
package foo

type t interface {
    Public()
}

type T interface {
    t
}
jnml@4670:~/src/tmp$ godoc tmp T

1. What did you expect to see?

use 'godoc cmd/tmp' for documentation on the tmp command 

type T interface {
    Public()
    // contains filtered or unexported methods
}

1. What did you see instead?

use 'godoc cmd/tmp' for documentation on the tmp command 

type T interface {
    // contains filtered or unexported methods
}

FTR: Importing the package and calling method Public on an instance of foo.T compiles just fine.
