I see this patch is marked "notmuch::moreinfo", but i don't see any
request for more info specifically, so i thought i'd fill that in here.

I don't know vim or ruby, but i would expect a patch like this to
contain at least a pointer to Ruby's Mail package's documentation about
a backward-incompatible change introduced in a certain version, if not
documentation about the expected upgrade path.  Can you provide those
pointers?

Thanks for offering fixes to the notmuch-vim codebase!
