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 */
}
