Hmm, I understand. My worry about this approach is the following: Now it
is very straightforward to start using notmuch. You only answer a few
questions when you run notmuch for the first time and then it works. If
we apply your patch, some additional configuration is needed and a
novice might not know how to do it.

So at least notmuch should tell the user what and where needs to be
configured. Or better, provide some sane default which can be overridden
in a way you want it.

That's only my opinion. I personally would have no problem with
additional configuration, but on the other side I like programs which do
not steel my time if it is not necessary.
