update-copyright is broken

[Brian C. Lane]

I think it was the change in commit a05d5d121b10f24 where it moved and
changed the exec code at line 1.

In parted with the latest gnulib I am getting these errors with 'make
update-copyright'

  GEN      update-copyright
Use of uninitialized value $_ in pattern match (m//) at 
./build-aux/update-copyright line 167.
Use of uninitialized value $_ in pattern match (m//) at 
./build-aux/update-copyright line 173.
Use of uninitialized value $ARGV in concatenation (.) or string at 
./build-aux/update-copyright line 285.
: warning: copyright statement not found

If I edit the new exec line to use the old one, but with -wSx, it works fine:

eval '(exit $?0)' && eval 'exec perl -wSx -0777 -pi "$0" ${1+"$@"}'
  & eval 'exec perl -wSx -0777 -pi "$0" $argv:q'
      if 0;

Thanks,

Brian
