            Bug ID: 194627
           Summary: misc/mc 4.8.13 does not save/restore the sub-shell's
                    screen on Ctrl+O and/or command execution

This happens due to rev 369133 incorrectly updates the
files/patch-lib__tty__win patch. Commit message says this patch file is changed
by upstream, but the truth is removed part is actually vital for sub-shell
screen save/restore to work properly.

The following patch reverts the change and fixes the problem for me:
