That search works without the macro, but not as a macro: notmuch
computes an empty `Query()` for this (as per `NOTMUCH_DEBUG_QUERY=1`).
I'm not sure whether this is intended or an artefact of the
implementation, since both the macro and the regex need
expansion/evaluation before being fed to xapian, and the order
matters.

Defining `D=(macro (dossier) ((tag ,dossier)))` and calling it with
`(D (rx ddddd))` works, btw (but is not what you want, obviously), so
something tells me lazy evaluation of macros is not completely lazy ;)
