How can I include code inside a quotation? [duplicate]

This is so bloody irritating - I finally just managed to format my answer, so code appears inside a quotation using <pre>, and I get "Your post appears to contain code that is not properly formatted as code":

Ok, so how do I properly format multiline code inside a quote? Obviously this:

> This is my quote line    Code Line 1    Code Line 2

... does not work, because it does not render the code inside the quote - the result is simply this:

This is my quote line

Code Line 1Code Line 2
