patch 9.1.0028: win32: Ctrl-D cannot be used to close a pipe

    patch 9.1.0028: win32: Ctrl-D cannot be used to close a pipe

    Problem:  win32: Ctrl-D cannot be used to close a pipe
    Solution: Properly detect Ctrl-D when reading from a pipe
              (GuyBrush)

    Enabling Ctrl-D for gvim pipeline input
    and apply defensive programming on account of PR #12752
    so that once PR 12752 is merged, CTRL-D will keep on working

    closes: #13849
