I'm not quite sure what this is supposed to demonstrate. In the cases
where you have specified the tab character correctly ($'\t'), it's
converted into a tab before matching is attempted. You can tell this
because in the cases where you have not, either the literal `$' gets
removed, or the literal instances of \t in the value of parameter are
removed. Since there are no tab characters in $parameter, no tabs get
removed when you specify $'\t' correctly.
