Thanks!

I think "info" is implied, so we can just do this:

-  out->print_cr("        and post-safepoint housekeeping. Use -XX:+PrintSafepointStatistics to
dissect.");
+  out->print_cr("        and post-safepoint housekeeping. Use -Xlog:safepoint+stats to dissect.");
   out->print_cr("  \"(N)\" (net) pauses are the times spent in the actual GC code.");

We don't care, since 12u is mostly dead anyway :)
