Sometimes 008_autocommands_spec fails like this:
[ RUN ] autocommands that delete and unload buffers: BufUnload, VimLeave: -- Output to stderr:
CMake Error at /home/travis/build/neovim/neovim/cmake/RunTests.cmake:53 (message):
functional tests failed with error: 1
The final :quit + wait() is a race. Use command() instead, which is
synchronous. Use command('silent! ...') everywhere else too, because
it's clearer instead of feeding input and clearing the expected errors
with CTRL-L.
