Thanks, done.

That sounds better, and I have renamed the variable in this iteration.

Thanks, I will keep that in mind.  I have also made some rearrangements
in the code to minimize delta.

In addition, I fixed an issue from the first iteration: in the first
iteration, the user would be prompted to revert buffer from disk if the
rename was in action; in this iteration this should no longer be the
case -- that is, the user should expect no difference between filenames
with extensions and without.

As pointed out in the commit message, two things remain: to ensure that
all write operations to extensionless zip archives behave correctly, and
to have some way to test that things continue to work in the future.
