Re: [PATCH v6 01/10] t0027: Make more reliable

> When the attributes of a commited file are changed and the file is otherwise
> unchanged, Git may not detect that the next commit may need to treat the
> file as changed.
> This happens when lstat() doesn't detect a change, since neither inode,
> mtime nor size are changed.
>
> Add a singe "Z" character to change the file size.
> Ignore it when comparing the files later.
