diag, not warn

Suggested patch for Catalyst::Manual::Tutorial::Testing:

Index: lib/Catalyst/Manual/Tutorial/Testing.pod
===================================================================
--- lib/Catalyst/Manual/Tutorial/Testing.pod (revision 8176)
+++ lib/Catalyst/Manual/Tutorial/Testing.pod (working copy)
@@ -314,7 +314,7 @@
temporarily insert a line similar to the following right after the
failed test:

- warn $ua1->content;
+ diag $ua1->content;

This will cause the full HTML returned by the request to be displayed.

Best,

David

It prevents the output from fucking up the harness.

I don't think the harness looks for anything on STDERR.

`diag` sends stuff to STDERR. So yes, it does.

Is that true? I don't know the suite well but a casual peek at
Test::Builder's guts looks like it goes to STDERR and STDOUT
alternately depending on whether the output was from failure or from
intentional calls. I think the reason it never interferes with test
harness is that the output is escaped/#commented.

Right. Which is why I suggest `diag` instead of `warn`.

Best,

David
