Error messages which mostly show (La)TeX code should be marked as a code block (indent with 4 spaces or the {} button), not as a quotation (>).

Error messages which mostly show file paths and no code, like File not found or similar errors, should be placed between <pre> and </pre> HTML tags to avoid wrong syntax highlighting.
