Term::ReadLine problem.

Using the example code in the SYNOPSIS on
http://search.cpan.org/~nwclark/perl-5.8.2/lib/Term/ReadLine.pm
works fine. However, adding a "\n" in $prompt makes the output
as follows:

Enter your arithmetic 
Enter your arithmetic 
expression:  

where the first line is underlined up to the "\n", and the two lines
below are completely underlined.
This happens with Term::ReadLine::Perl.
With T::R::Gnu, this problem does not occur.
