Re: [PATCH v6 0/4] Add support for mailmap in cat-file

> Changes in v6:
> - The function rewrite_ident_line() returns the difference between the
>   new and the old length of the ident line. We were not using this
>   information and instead parsing the buffer again to look for the line
>   ending. This patch set starts using that information to update the
>   buf_offset value in commit_rewrite_person().
> - This patch set also tweaks the commit_rewrite_person() so that it is
>   easier to understand and avoids unnecessary parsing of the buffer
>   wherever possible.
