Parameter expansion and variable expansion are the same thing.  A variable
is a parameter denoted by a name.  The man page is inconsistent in its
usage -- some places it says "parameter and variable expansion" -- but
there's no difference.  Posix, for example, does not use the term
variable expansion at all.
