python-zstandard: blacken at 80 characters I made this change upstream and it will make it into the next release of python-zstandard. I figured I'd send it Mercurial's way because it will allow us to drop this directory from the black exclusion list. # skip-blame blackening Differential Revision: https://phab.mercurial-scm.org/D7937
