Another option occured to me that is consistent at least with notmuch
tag and notmuch show would be to support the following transitional
syntaxes

        notmuch dump file
        notmuch dump file [--] search terms
        notmuch dump -- search terms

the first two could then be deprecated, and eventually the syntax

    notmuch dump search terms 

could be enabled.

the question of whether to support 

    notmuch dump --file foo.txt

or something like 

   notmuch --stdout=foo.txt dump

could be dealt with later.
