Ian Lance Taylor fc821667dd os: change Readdirnames doc to follow that of Readdir
The two methods act the same, so make their documentation similar so
that people don't think they act differently.

// Readdir reads the contents of the directory associated with file and

// by Lstat, in directory order. Subsequent calls on the same file will yield
// further FileInfos.

// If n > 0, Readdir returns at most n FileInfo structures. In this case, if
// Readdir returns an empty slice, it will return a non-nil error
// explaining why. At the end of a directory, the error is io.EOF.

// If n <= 0, Readdir returns all the FileInfo from the directory in
// a single slice. In this case, if Readdir succeeds (reads all
// the way to the end of the directory), it returns the slice and a
// nil error. If it encounters an error before the end of the
// directory, Readdir returns the FileInfo read until that point
// and a non-nil error.
