I'm not sure, but I never clobber files that way...

I think if it's significantly reduced, it does warn. But I'm not sure what
that's based on.

The current behavior, whatever it is, does not lose contents that get
accidentally deleted from disk.  I'm not sure what happens if you cat
/dev/null onto your code.
