Comment 6 for bug 87058

I propose changing the message when not using Javascript to:

The tag "superdupernewtag" hasn't been used by Launchpad Bugs before. (Create the new tag)

This fix solves the grammatical issues raised in bug 106924 and the use of the verb "create" rather than "define" should solve Chris' issue.

It is interesting to note that the Ajax version just creates it without asking.
