Daniel Kahn Gillmor 0ada2a05c9 cli: some keyword options can be supplied with no argument
We might change some notmuch command line tools that used to be
booleans into keyword arguments.

In that case, there are some legacy tools that will expect to be able
to do "notmuch foo --bar" instead of "notmuch foo --bar=baz".

This patch makes it possible to support that older API, while
providing a warning and an encouragement to upgrade.
