When viewing potentially hostile html, it may be helpful to see what a given link was pointing to. This new injector takes the href attribute and adds the text after the link, and deletes the href attribute. Other forms of display could easily be contrived, but this seems to be a good basic way to present the information. Signed-off-by: David Morton <mortonda@dgrmm.net> Signed-off-by: Edward Z.
