Unexpected output of "notmuch new --quiet"

Because I do not agree with Notmuch's notion of what a non-mail file
is. All files the Dovecot server uses for its own metadata are placed
outside of "cur", "new", and "tmp".

My understanding of the Maildir structure is that only these three
subfolders in a given directory may contain mail files, so I expect
Notmuch, as a default behaviour, to ignore whatever is stored outside
of these subfolders.
