Perhaps it never did work?  It looks like this function to date is used
only for properties, where I assume each message has just one or two?
With just a few elements a buggy binary search can do surprisingly well.
Don't ask me how I know this.  ;-)

Perhaps some unit tests for _notmuch_string_map would be worthwhile?

Looks good.
