I'm just noticing that 'notmuch help ...' outputs to stderr, which
isn't terribly intuitive. For example, the obvious invocation:
notmuch help | less
=2E..isn't terribly helpful.
I've attached a patch that lets usage() take a FILE * argument so that
you can output to stderr in response to usage errors, and stdout in
response to an explicit request.
