Subject: Use conditional case for diff reports (#1226)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/a02829bea1452e0db150eec88c2d99eaf162aa72?hp=9ef8e6c9b0090d787953bcd3c46a8942483fcc6b

Use conditional case for diff reports (#1226)

When --diff flag is used, black will now use the
conditional case in the Report output: eg "would
be reformatted"
