It turns out to be inconvenient to delete the downloaded datafiles with
distclean, so I propose a new target which does that instead.
The closest conventional target is 'maintainer-clean'; the difference
here is that having the original source tarball is not enough to
reconstruct these files.
distclean: clean
rm -rf $(DISTCLEAN)
+.PHONY: dataclean
+dataclean: distclean
+ rm -rf $(DATACLEAN)

notmuch_client_srcs = \
command-line-arguments.c\
debugger.c \
CLEAN := $(CLEAN) $(dir)/tmp.* $(dir)/log.*
DISTCLEAN := $(DISTCLEAN) $(dir)/corpus $(dir)/notmuch.cache.*
+DATACLEAN := $(DATACLEAN) $(TXZFILE)
download-test-databases: ${test_databases}
-DISTCLEAN := $(DISTCLEAN) ${test_databases}
+DATACLEAN := $(DATACLEAN) ${test_databases}
