Outline view creates multiple "main" on Windows

[waxhead]

Seems this is visible in 0.70 and 0.72 on windows, as I can't replicate this issue on ubuntu 10.04.

To replicate this, open a new document, type in

use strict;
use warnings;

and then enter multiple times, you should start to see main appear multiple times in the outline window.

It does appear that this might be a windows only issue.
