I see what you're saying. I'm not sure this is a problem that needs
to be solved by changing the editor interface, though; I think there
may be enough information there to detect this case anyway.

My apologies for having to defer so many issues till "tomorrow" (two
days I've done that now). There's a lot of other noise going on over
here right now, and technically I don't even work on Wednesdays :-),
so at a certain point I just punt until the next day, heh.

I think we can get all this stuff resolved during the day tomororw,
though, and get back to coding. Ben and I are trying to organize
these various threads into a list of specific issues and tackle them
one by one.

Yeah, that's probably a meaningless question :-). The directory
records its version as being v6 until you do "update .", but you could
end up with every file in the directory being at some version other
than v6 before that happens.
