<p>Shift the accumulator right by <em>n</em> bits. When <em>n</em> is negative shift the accumulator left by <em>-n</em> bits. If |<em>n</em>| ≥ 32 then <code>A</code> is set to zero.</p>
This is buggy. Watch for the extra space in the second "shift the" and how "by -n" gets "by-n".

This is the same HTML as above, but newlines replaced by spaces. And now all of a sudden it does the right thing.
