+Patch 7.4.876
+Problem:    Windows7: when using vim.exe with msys or msys2, conhost.exe
+            (console window provider on Windows7) will freeze or crash.
+Solution:   Make original screen buffer active, before executing external
+            program.  And when the program is finished, revert to vim's one.
+            (Taro Muraoka)
