I think we released an alpha tarball that fails make check-spaces. nick says it's fine with him if we make 'make test' include make check-spaces. I think a slightly better option is to make 'make dist' include it. Is it as simple as changing "dist: check" to "dist: check check-spaces" in Makefile.am? Turns out not to be quite that simple -- that runs check-spaces but doesn't stop if check-spaces is unhappy.
