But that is what -m (--canonicalize-missing) is _documented_ to do. If
you want to fail for missing files, use -e (--canonicalize-existing); if
you want to probe whether a file name can be created (that is, the
directory portion exists), use -f (--canonicalize).

Sorry, but I don't see this as a bug, but a feature - the fact that we
have three different options with three different levels of existence
checks was intentional. I'm closing this bug, but you can feel free to
add further comments or questions.
