no need to highlight very short code blocks:
- content inside might not be code, some users still use code blocks
for plaintext quotes
- language detection will almost certainly be incorrect
- even if it's code and the language is detected, the user will
be able to mentally format small amounts of code themselves
feel free to change the threshold number
