Subject: Output something when no files are reformatted (#190)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/2d9eaafa97e967c8974a6321dcc442a90192140f?hp=2d9eaafa97e967c8974a6321dcc442a90192140f

Output something when no files are reformatted (#190)

Just executing ``black`` without any argument does not print any message
to stdout or stderr. It's rather confusing, because the user doesn't
know what happened.

In ``len(sources) == 0`` case, black now prints ``No paths given. Nothing to
do``.
