Improve tree_entry_interesting() handling code
t_e_i() can return -1 or 2 to early shortcut a search. Current code may use up to two variables to handle it. One for saving return value from t_e_i temporarily, one for saving return code 2. The second variable is not needed. If we make sure the first variable does not change until the next t_e_i() call, then we can do something like this: int ret = 0; while (...) { if (ret != 2) { ret = t_e_i(); if (ret < 0) /* no longer interesting */ break; if (ret == 0) /* skip this round */ continue; } /* ret > 0, interesting */ } Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
