Restricting this feature further, maybe through a configuration
property or even special casing the EDITOR is also IMHO a good idea.
I think just doing this when we run the editor may be the way to go as I
think it is only that case that can mess up the terminal.
If it only happens with certain versions of vi / vim, perhaps Git could come
with a front end program that saves the tty state, runs vim, and restores the
tty state. (Or set this up so that the program can run any editor.)  Then add
a FAQ entry if needed: "if your editor goofs up the terminal, insert this front
end program".
Putting myself into an end-user's shoes, I would much prefer not to be
asked to do extra work and I imagine that the millions of other users who
go with Git's default editor have the very same preference.

Just like we default to `LESS=FRX` for Git's default pager, and just like
we special-case `less` and `vi` in `git grep -O<program>`, it makes sense
to special-case `vi` when saving/restoring the terminal because we know it
helps users.

And by "special-case", I want to say that Git should provide a paved path
to success, not a workaround that users still have to configure manually.

Ciao,
