Message:

Add a comment about nested command substitution

"The command below shows an example of nested command substitution

using two methods: backquotes and a $() construct. It could be
rewritten using the same method for both substitutions, but is
shown this way to demonstrate how they can be mixed. Generally
the $() method is preferred."
