Subject: test: add known broken test for nondestructiveness of count
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=169e29d43192a9336869c4e6431203da7c85ef2d;p=notmuch.git

test: add known broken test for nondestructiveness of count

Thanks to Lucas (id:147263183913.27784.12274024193186585889@mbp) for the
bug report and the test case.

I decided to use the python version because the python bindings could
use more exercise.
