cs-bisection-step: Limit size of revision log included in reports

There is a limit in cr-daily-branch, but none in cs-bisection-step.

adhoc-revtuple-generator could usefully have this built in but that's
not so simple, so do it again here.  We already slurp the whole thing
into core so from a resource usage point of view we might as well do
the length check here too.
