In the [new] section, "tags=;" will cause notmuch to create empty tags
that are fairly hard to remove from the command line.

After some help on #bup, here's what I came up with to remove them,
though it assumes that the empty tag "+ " will always be first in dump's
output:

  notmuch dump --format=batch-tag 'tag:""' | perl -pe 's/^\+ //' \
    | notmuch restore --format=batch-tag

And note that you have to use restore, "notmuch tag --batch" doesn't
appear to accept "- " as a tag, even though dump will produce "+ ".

Hope this helps
