Lavender

A slightly more compromising Python code formatter, based on the latest stable release of Black (20.8b10 at the time of writing).

Differences from Black

The default line length is 99 instead of 88 (configurable with --line-length).
Single quoted strings are preferred (configurable with --string-normalization none/single/double).
Empty lines between classes and defs are treated no differently from other code. The old behavior, which sometimes inserts double empty lines between them, remains available via --special-case-def-empty-lines.
The Vim plugin configuration variable for line length is named g:lavender_line_length instead of g:lavender_linelength, for consistency with the other configuration variable names.
