"Returns a list of pathnames to messages in a maildir. The messages are
returned in no guaranteed order. Note that this function doesn't fully
implement the behavior prescribed by maildir(5): It only looks at `cur`
and `new` and won't clean up `tmp` nor move files from `new` to `cur`,
since it is strictly read-only."
