Unable to import file with more than 2 import paths

[tfeng]

The code snippet below in parser.go has a bug. It doesn't try to import the file when it exists only on the 3rd import path or later.

accessor = func(name string) (io.ReadCloser, error) {
        var ret error
        for _, path := range paths {
                f, err := acc(filepath.Join(path, name))
                if err != nil && ret == nil {
                        ret = err
                        continue
                }
                return f, nil
        }
        return nil, ret
}
