The old text was definitely not self-explanatory; it made me more confused than 
enlightened.
But let's try again. What about:

Return VALUE with its bits shifted left by COUNT.
If COUNT is negative, shifting is actually to the right.
Values are shifted as an infinitely wide two's complement representation; each 
shift step multiplies (left-shifting) or divides (right-shifting) the value by 
two, rounding down.
VALUE and COUNT must be integers.
