builtin/remote: fix leaking strings in `branch_list`
The `struct string_list branch_list` is declared as `NODUP`, which makes it not copy strings inserted into it. This causes memory leaks though, as this means it also won't be responsible for _freeing_ inserted strings. Thus, every branch we add to this will leak. Fix this by marking the list as `DUP` instead and free the local copy we have of the variable. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
