Displaying of counterexamples enhanced.
When counterexample is displayed interleaved with source code, only the part of the source code from the beginning to the line of the last counterexample element is displayed and the focus in the editor is on the end of that source code. Textual counterexample (without interleaving with source code) is not displayed by default. There is a debug flag debug_show_text_cntexmp that enables such display.
