builtin/worktree: fix leaking derived branch names
There are several heuristics that git-worktree(1) uses to derive the name of the newly created branch when not given explicitly. These heuristics all allocate a new string, but we only end up freeing that string in a subset of cases. Fix the remaining cases where we didn't yet free the derived branch names. While at it, also free `opt_track`, which is being populated via an `OPT_PASSTHRU()`. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
