Thanks Dirk,

This is even handier than I expected.

I've pushed this now, but followed up immediately with a (totally
trivial) change to reduce code duplication, and then a (slightly more
major) change to define the controlling variable with defcustom so that
the user can find the variable in the customize screen for notmuch.

I also renamed it to notmuch-poll-script so you'll need to update your
setting for this feature to work.
