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.
