Re: [PATCH 01/19] Add struct pathspec

> This struct for now is just a wrapper for the current pathspec form:
> const char **. It is intended to be extended with more useful
> pathspec-related information over time.
>
> The data structure for passing pathspec around remains const char **,
> struct pathspec will be initialized locally to be used and destroyed.
> Hopefully all pathspec related code will be gradually migrated to pass
> this struct instead.
