revision: keep topo-walk free of unintersting commits
When updating the topo-order walk in b454241 (revision.c: generation-based
topo-order algorithm, 2018-11-01), the logic was a huge rewrite of the
walk logic. In that massive change, we accidentally included the
UNINTERESTING commits in expand_topo_walk(). This means that a simple
query like
git rev-list --topo-order HEAD~1..HEAD
will expand the topo walk for all commits reachable from HEAD, and not
just one commit.
This change should speed up these cases, but there is still a need
for corrected commit-date for some A..B queries.
