Ah, well you learn something new every day :) That can actually come in
very handy now that I know the string for adding is expanded before the
remove takes place - I thought they were expanded and processed at the same
time, thus meaning remove kicks in before add, and so you can't reference
any removed headers in your add statement.

Thanks for the info :)
