Makes sense. Between the location of the original strbuf_addf()
call and the new strvec_pushf() call, nobody mucks with *opts so
this change won't affect the correctness. We no longer use the
extra strbuf, and upon failing to open the rebased-patches file,
we no longer leak the contents of it. Good.
