obsolete: speed up computation of bumped revset

Browse Source 
Speed up the computation of the bumped revset by using the not public() revset.
In another patch series, we optimized the not public() revset. Together,
this cuts the cost of the computation of bumped() from 17% of the total time of
smartlog on our big repo to under 0.1% of the total time.
