suppose, during execution width comes less than 8 like 5, then we would like to run our code section which handles the reaming width (_end_col:) not the whole code (handle multiple of 8 and renaming width part, it will computed twice in this case and corrupting some (8 - widthleft) dst[] old values which is being used with 'pblenvb' instruction.This is why we have put a check. if width is always >= 8 you are right, we don't need to put the check.
