automake warning useless use of /d modifier in transliteration in Wrap.pm

[Jay K]

warning, not error, seems to work ok


bash-4.1$ autoreconf
Useless use of /d modifier in transliteration operator at 
/home/jayk/share/automake-1.11/Automake/Wrap.pm line 58.



bash-4.1$ automake --version
Useless use of /d modifier in transliteration operator at

sub tab_length($)
{
  my ($txt) = @_;
  my $len = length ($txt);
  $len += 7 * ($txt =~ tr/\t/\t/d);       # here 
  return $len;
}


I guess the point is to count the characters, not change them, or something.
