I forgot to note email addresses are also handled as phrases
unconditionally.  In any case, pushed as

    searchidx: fix -Lmedium for IDs and filenames

    This fixes "m:", "l:", "f:", "t:", "c:", "dfn:", and "n:" search
    prefixes under indexlevel=medium when mixed with indexlevel=full
    inboxish.  We need positional data for Message-IDs, List-Id,
    email addresses and filenames for exact matches, though we still
    want to support wildcards.

    Fortunately the storage cost is still small as these prefixes
    tend to be small compared to message bodies.  These are NOT
    boolean terms since wildcard support and partial matching is
    desired.
