What the title says. If the title of a filter is "[[Cake]]", then what will be shown in warnings when referencing the filter is "<a href="cake">Cake</a>" without actually working.

Ideally titles of filters would just be plain text. The [[Cake]] doesn't need to link anywhere, but it should display as [[Cake]] instead of the non-functional HTML code probably.
