Output:

No 1 is ok.
In No 2 the second line is outside the <pre>, but not parsed as wikisyntax. With <syntaxhighlight> instead of <pre> two additional </div>s appear (unless tidy removes them again).```
No 1 is ok. In No 2 the second line is outside the <pre>, but not parsed as wikisyntax. With <syntaxhighlight> instead of <pre> two additional </div>s appear (unless tidy removes them again). No 3 is like No 2, but the # is interpreted as wikisyntax for <ol>.
