Some times folks put the code blocks first, and the question second. The CRLF in code blocks is ignored, which makes the summaries usually worthless. Also, it is code, and not a description of the problem, then the summary is again usually worthless.
Do not include code blocks in abbreviated question summaries on the question listing pages.
Then again, we could just go off and reformat other people's questions, but that seems unnecessarily invasive for such a minor 'problem'.
