Although you have one too many sets of (), there is still a bug here.

         $ notmuch config set squery.D '(macro (dossier) (tag (regex ,dossier))'

also doesn't work.  Apparently both for regex and wildcard expansion I
did not do macro parameter expansion. In the regex case the regex
matching for tags actually happens at query construction time, so that's
why it ends up as an empty query (presumably none of your tags starts
with ,dossier).

Anyway, I think I know how to fix this, it will mean that in the corner
case of a regex starting with a comma, we'll have to use (regex ",foo").
