patch 8.0.0627: "gn" selects only one character with 'nowrapscan'

commit https://github.com/vim/vim/commit/add8dce38de65a0c64e8f54d6bdcadb45a8de2cf
Author: Bram Moolenaar <Bram@vim.org>
Date:   Mon Jun 5 19:56:04 2017 +0200

    patch 8.0.0627: "gn" selects only one character with 'nowrapscan'

    Problem:    When 'wrapscan' is off "gn" does not select the whole pattern when
                it's the last one in the text. (KeyboardFire)
    Solution:   Check if the search fails. (Christian Brabandt, closes #1683)
