Yeah but those are actual bugs, where leaving data behind on the user's terminal's alternate screen IS NOT. It's designed to work that way, and the design is correct... it's largely the reason alternate screens exist. Re-dumping the data to your printer would be a bug in your terminal. If your terminal has a bug where that's a problem, any related security issue is in the terminal, NOT in Mutt. I think you can make a pretty good case that Mutt should work around stupidity in broken e-mail clients (like all the various brain damage in Outlook), since it is directly related to, and directly affects, Mutt's primary function. But I don't think you can make a good case that Mutt should try to work around every possible bug in every possible software component of your system, since that is a practical impossibility. -- Derek D.
