So, I can kind of see why opening the preview window would fire off
two events...if it is implemented by opening the window, switching to
the window, and switching back.
The option window makes much more sense now, after looking at
optwin.vim. There are a _lot_ of "exe 'normal! <C-W>...'" commands in
there. Are there any plans to re-implement this using setwinvar,
settabwinvar, setbufvar, etc. instead? If not, is there some reason
not to do this, or has it just not been suggested yet?
