Subject: [PATCH] GPGCleanup: Allow the buffer to be hidden on exit

When Vim has decided it can exit, GPGCleanup forces a blank buffer to
take over the screen so contents aren't visible in scrollback.  However,
if the buffer is modified and 'hidden' isn't set then the command will
fail.

Force the buffer to be hidden, so this is avoided.
