Re: [PATCH] grep: use return value of strbuf_detach()

> Append the strbuf buffer only after detaching it.  There is no practical
> difference here, as the strbuf is not empty and no strbuf_ function is
> called between storing the pointer to the still attached buffer and
> calling strbuf_detach(), so that pointer is valid, but make sure to
> follow the standard sequence anyway for consistency.
