Occasionally, a user does this deliberately, when they're trying to just
add or alter some tags. Dedicated tag editors, in general, don't create
a new file. So, we've had a few users who inadvertently destroyed their
input. Implementing this will avoid those cases.
This is useful, independently of whether -y was applied. An exemption
can be made for streaming input/outputs.
