- imul and lmul mention "mathematical sum of the two values" not the mathematical multiplication!

- lsub mentions "mathematical sum of the two values" not the mathematical difference! Note that lsub's close friend, isub, was corrected in SE 5.0 to say "mathematical difference".

- lushr description doesn't mention s, but its notes do. lushr should follow its friend iushr by identifying s as the shift distance: "A &long; &result; is calculated by shifting &value1; right logically ***by s bit positions***, with zero extension, ***where s is the value of*** the low 6 bits of &value2;."
