OK, but the patch proposed works both for people who want to be notified
of this problem, and those that don't (with appropriate shell wrapping
checking the return code).  That seems better than hiding it for
everyone. And certainly an improvement on the status quo. A possible
future enhancement would be a flag like notmuch insert has to control
the treatment of these errors.
