Reindl is using fgrep (implied by the -F flag), so I would think \n is
interpreted literally.  I would agree with your suggestion to use 

  $ grep -E "<?$"

Another recommendation would be to use -print0 and pipe to xargs -0.
Using the -exec flag for something like this might be significantly less
efficient.
