Recently added, was writing hashes out in a salt-safe manner, within dynamic. This was done to work around some known issues, such as \n : $ NULL, or other naughty characters being contained within the salt field, causing JtR's string handling and field splitting functions to fail. Well, there were 2 places within loader which required changes. One was in load_pot_line() the other (which was not done), as in show_pot_line(). I am not sure why the 2 functions, but I had only added code to the load_pot_line. This also affects the j7 release candidate I have made some changes here also. I may need to talk to magnum offline a little, to figure out just how to push this out. It may be best if I make a patch for j7-rc, for jumbo, and for bleeding. Unfortunately, I think that all of these may have some collision issues, especially within the loader code, which is different between the versions.
