Revert "connected: do not sort input revisions"

This reverts commit f45022dc2fd692fd024f2eb41a86a66f19013d43,
as this is like breakage in the traversal more likely.  In a
history with 10 single strand of pearls,

   1-->2-->3--...->7-->8-->9-->10

asking "rev-list --unsorted-input 1 10 --not 9 8 7 6 5 4" fails to
paint the bottom 1 uninteresting as the traversal stops, without
completing the propagation of uninteresting bit starting at 4 down
through 3 and 2 to 1.
