Subject: vim: add "--skip-string-normalization" support (#310)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/e5f5d54a224254bb7227f0379d0af0dde81aff37?ds=inline

vim: add "--skip-string-normalization" support (#310)

Since 18.6b0 was released, there has been a new option to skip string
normalization when Black is called, but it wasn't able to be specified
from within the vim plugin. This commit adds that functionality.

Tested with g:black_skip_string_normalization set to 0 (off) and 1 (on).
