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

["René Scharfe" <l.s.r@web.de>]

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.
