Implementation wise this series now looks OK to me; I think the dequote
routine could be slightly clearer, but it's a bit subjective at this
point.

IMHO the real question is if we like (or can live with) the resulting UI
for batch tagging.  Mark ( id:87ehid5h64.fsf at qmul.ac.uk ) brings up the
question of whether tags with newlines should be somehow supported in a
batch-tagging context. The other UI issue I'm aware of is the fact that
tags with spaces needed to be quoted in two different ways for tag
operations and for queries.  A relatively smooth upgrade path would be
to support Xapian quoting for tag operations in the future.
