sub-list: better handling of from value of t.
* lib.c (sub_list): If from is t, then just return nil.
Do not reset it to nil in this case. After this we know from
is not nil; we don't have to check for this inside one
loop. That loop was wastefully iterating over the list in the
from == nil case only to calculate nil.
