Re: [GSoC][RFC PATCH v4 0/5] Add refs list subcommand

> Hello everyone,
> 
> This is the fourth version of the patch series that introduces the git
> refs list subcommand.
> 
> Changes in v4:
> 
>   - Implemented architectural refactoring. The core logic of
>     for-each-ref now resides in a shared helper function, and both
>     for-each-ref and refs list have been simplified to thin wrappers
>     around it.
> 
>   - The usage strings have also been refactored. The common options
>     are now defined in a shared macro in a new for-each-ref.h header.
> 
>   - The patch series has been further split to cleanly separate the
>     preparatory refactoring commits (for both the C code and the
>     AsciiDoc documentation) from the commit that introduces the new
>     feature.
> 
>   - As a beneficial side-effect of unifying the usage strings, this
>     series now fixes a pre-existing inconsistency between the --help
>     output and the man page for for-each-ref. This allows a known
>     breakage for it in the t0450 documentation test to be removed.
