Eek, sorry I should have said I used texinfo-6.1-4.fc25.x86_64

The warning is caused by the @exdents (which occur nowhere else in the file).
The code producing the warning is:

      if ($line->{'indent_length'}) {
        $result .= ' ' x ($line->{'indent_length'} - $line->{'counter'});
        print STDERR "INDENT.L($line->{'counter'})\n" if ($line->{'DEBUG'});
      }

So 'counter' must be more that 'indent_length' which must be non zero.
It's only a warning so it doesn't matter really.
I'll leave it up to you if you want to leave the @exdents in place
