Re: [PATCH 3/5] Rework unquote_c_style to work on a strbuf.

> If the gain is not obvious in the diffstat, the resulting code is more
> readable, _and_ in checkout-index/update-index we now reuse the same buffer
> to unquote strings instead of always freeing/mallocing.
>
> This also is more coherent with the next patch that reworks quoting
> functions.
>
> The quoting function is also made more efficient scanning for backslashes
> and treating portions of strings without a backslash at once.
