From Apple's (older) AppKit release notes (in the Section Changes  
between OpenStep 4.0 and OpenStep 4.1,
see http://developer.apple.com/mac/library/releasenotes/cocoa/ 
AppKitOlderNotes.html#OpenStepNotes):

  NSApplication: ... In addition, all command-line options that are  
not defaults options (meaning
  a pair of arguments where the first one starts with a "-") are now  
treated as file names to be
  opened, as if they were prefixed with -NSOpen.

So it is not specific to document based applications (which did not  
exist at that time anyway).
