With input.select this allows building nested submenus without the
flicker of console quickly closing and reopening, and also doing
multiple selections, to e.g. cycle through different values of a
property, or increase a property multiple times.
With input.get this is used to change the default behavior to closing by
default on submit. It was argued by avih that this is more useful, and
indeed Github code search shows that everybody is calling
input.terminate() unconditionally on submit, so the impact of the change
should be low, and restoring the old behavior is as easy as passing
keep_open = true, which is just ignored in older mpv versions.
