I agree about preferring $() over backticks, but msh doesn't like $()
and does like backticks. Remember, this man script is meant to be an
extra for busybox. I don't see it being used without busybox and thus
busybox compatibility is my priority.  I suppose the best thing to do
is add support for $() in msh. Anyone else care to comment?
