[Bug 1351050] [NEW] Weird iteration order when displaying multiple images

[Rickard Westman]

Public bug reported:

The "display" command takes multiple image files on the command line.
By using the File/Next command, those files used to be displayed one by
one in the sequence given, but in this version, something weird happens
instead which is easiest to explain through an example.  Consider this
command line:

  display 1.png 2.png 3.png 4.png

I would now expect images to be displayed in the order given, i.e. 1 2 3
4.  Instead, the actual order observed is:

  1 1 2 1 2 3 1 2 3 4

I know this worked as expected in older versions of Imagemagick, but I
unfortunately don't know exactly how far back you would have to go to
get the correct/sensible behavior.
