just a thought on the other side of the coin: it is nice to have
reference code to copy from once we all figure out best practices. I
think the issue is similar to removing redundant `cat`s. maybe it's
pedantic but it makes us better next time we have to write a script--
as long as it is done for self education and not for useless 'OMG!
wasted 2ns!' crusades.
