Can apex-diff include all page javascript?

[ashleyghooper]

Recently while diffing a couple of applications with apex-diff we found that for pages with a lot of javascript in the page_html_header box, the field seems to be truncated at around 4000 characters, making this an unreliable tool for comparing applications with in-page javascript.

Yes, ideally, the javascript should be kept in external script files, but nonetheless, for supporting legacy applications being able to compare larger elements in full would be very helpful.
