For traceback argument printing, we want to print at most 10 words, then print "..." if there are still more args and/or fields. The current code has off-by-one error that for 11 non-aggregate typed args, it prints the first 10 but without the "...". Also, for aggregate-typed args, in some cases it may print an extra "..." when there is actually no more fields. The problem for this is that visitType return false (meaning not to continue visiting) if it reaches the limit anywhere during the recursive visit. It doesn't distinguish whether it has printed anything for the current arg. If it reaches the limit before it prints anything, it means that we're visiting the extra arg/field, so the caller should print "..." and stop. If it prints something then reaches the limit, however, the caller should keep going, and only print "..." at the next iteration when there is actually an extra arg/field. This CL does so. Fixes #47159.
