t/helper/test-fast-rebase.c: don't leak "struct strbuf"

avar · gitster · commit 78fbea3d8c30 · 2022-04-03T15:03:07.000-07:00
Fix a memory leak that's been with us since f950026 (fast-rebase: write conflict state to working tree, index, and HEAD, 2021-05-20) changed this code to move these strbuf_release() into an if/else block. We'll also add to "reflog_msg" in the "else" arm of the "if" block being modified here, and we'll append to "branch_msg" in both cases. But after f950026 only the "if" block would free these two "struct strbuf". Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
