If you wanted to be fairly careful, perhaps test for
exists(".notmuch/.xapian/flintlock" or ".notmuch/.xapian/iamchert"), or
some other very specific test.

Not sure.  Though I'm wondering if I may have suggested we could add a
notmuch specific token file, i.e. .notmuch/this-really-is-a-notmuch-dir,
which lead to someone else suggesting we could just use .xapian.

Of course broadly speaking, ".xapian" might be a legitimate maildir too,
but ".notmuch/.xapian" seems fairly unlikely.

In any case, while I might prefer a very narrow test (as long as it
wasn't unduly expensive), all of the proposed solutions would have
handled my situation.

Thanks
