Nothing is wrong with a comment that elucidates the purpose of the instruction. 
A comment that merely translates the instruction is worse than useless.

I can already figure out that the instruction will be executed; tell me *why* 
in the comment. How does it fit in the broader scheme of things? Where are the 
EX instructions and what is the significance of the lengths that they use?

What's wrong with a comment?
