/**\file
 * Registers custom listener that asks for captured stdout/err
 *
 * Running the binary with this listener, and asking for multiple _noncapturing_
 * reporters (one would be sufficient, but that would also mean depending on
 * implementation details inside Catch2's handling of listeners), we check that
 * the listener gets redirected stdout, even though the reporters didn't ask for
 * it.
