I had similar testing that was strange...  I really do not understand 
how you can strip a file without r+w permissions.  But my testing seemed 
to indicate that you can strip a -r+w file.  And you seem to be able to 
strip any file if you are root.  And yes, from memory, fakeroot appears 
to be somewhere in between.

I think the current patch at least avoids any errors and the associated 
output during stripping files which is an improvement.  But I wonder if 
it should be more clever and change the permissions of files before 
striping to ensure all files get stripped and then revert afterwards.
