Right, so you didn't have database.path in your config file before right?
Doesn't the default notmuch setup set that for you?

It wouldn't be too hard to change vim to use 'notmuch config list' to get
its configuration information, but as mentioned a library would be much
nicer.

Anyone have any thoughts on this?  How does the emacs client do it?  If
the config list method is superior I'll write up a patch for it.
