obsolete: simplify relevantmarker

Drop duplicate assignment from a merge failure. Save
one loop iteration by exploiting that pendingnodes will
be seennodes after the first round anyway, so just
pre-initialize the set accordingly. From Anton Shestakov's
review on !867. Performance difference for my test case is
in the noise.
