To the extent of my knowledge, yes; I left that in since the original
tests I was replacing with this script also used this terminator:

-// { dg-output "default std::handle_contract_violation called: .*.C 21 test<double>::fun .*(\n|\r\n|\r)*" }
+// { dg-output {contract violation in function test<double>::fun at .*:21: b > 0(\n|\r\n|\r)*} }
+// { dg-output {\[continue:on\](\n|\r\n|\r)*} }

That could easily use the simpler [\r\n]* form too:

% regexp {^[\r\n]*$} "\r\n\n\n"
1

Feel free to swap that in too.

Thanks, have a great night.
