builtin/blame: fix leaking prefixed paths
In `cmd_blame()` we compute prefixed paths by calling `add_prefix()`, which itself calls `prefix_path()`. While `prefix_path()` returns an allocated string, `add_prefix()` pretends to return a constant string. Consequently, this path never gets freed. Fix the return type to be `char *` and free the path to plug the memory leak. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
