redo-log: sometimes print a (resumed) line after ending a level of recursion.

Browse source 
If A calls B, and B produces stderr output, and then A wants to produce
output, the resulting log would be confusing: we'd see 'redo A' and
then 'redo B' and then B's output, but no indicator that B has ended
and we're back in A.  Now we show 'redo A (resumed)' before A's output.

If B didn't produce any output, or A doesn't produce any output, we
don't bother with the (resumed) line.  This seems nice, as it doesn't
clutter the log when there is no ambiguity anyway.
