Of course, a day after I push this (and after a couple of years of
poking at this library), I realized that there is a
backwards-incompatible change in behavior, even if you don't turn query
parsing on.

nnir had `nnir-imap-default-search-key', which let you set a default
search key (like "body" or "subject"). If you wanted to use a different
key you had to give a prefix argument to the search command. Or you
could set that option to "imap" and explicitly enter the search keys.

The prefix argument now toggles "raw" searches vs parsed, and raw
searches of imap groups always behave as with the "imap" value above.
Ie, you can no longer specify a single default search key.

I've added an obsoletion note to this effect, but it could still be
surprising for people who were using that feature. If it bothers anyone,
please tell me and I'll think of a way to get the behavior back in
there.
