New Revision: 218328
URL: http://svn.freebsd.org/changeset/base/218328

Log:
  MFC r217847: sh: Clean up some old comments:
  * There is no plan for an alternative to the command "set".
  * Attempting to unset a readonly variable has not raised an error for quite
    a while, so the order of unsetting a variable and a function with the same
    name does not matter.
