Re: [PATCH 0/6] clean up parsing of maybe_bool

> When we want to parse a boolean config item without dying on error, we
> call git_config_maybe_bool() which takes two arguments: the value to be
> parsed (obviously) and a `name` which is completely ignored. Junio has
> suggested to drop `name` and rename the function [1]. That effort even
> started shortly after that, by introducing git_parse_maybe_bool(). The
> new function currently only has a single user outside config.c.

> Patch 5 of this series deprecates the old function and updates all
> callers to use git_parse_maybe_bool() instead. Patch 6 is a final
> cleanup: one of the converted callers suddenly had an unused argument.
