Nit: We want to have full sentences in commit messages. Those sentences
should start with an upper-case letter and end with punctuation.

Hm. I'm not exactly sure what "false complaints" you are talking about
here. The benefit of `test_path_*`()` over `test -[efd]` is that they
actually print information _why_ they have failed, which may help devs
to figure out what's happening. So it's kind of the opposite of what you
say in the commit message: we're now printing _more_ output, not less.

This isn't quite equivalent: we've been checking that the path is not a
directory before, but now we verify that the path doesn't exist. It's a
sensible change in this context though as our new assertion is stronger
than the old one, but it might make sense to point out in the commit
message.

We tend to use `test_path_is_file` rather than
`test_path_is_file_not_symlink`, but I don't mind it too much.
