doc: fix unmatched code fences in git-stripspace

The asciidoctor renderer is more picky than classic asciidoc,
and insists that the start and end of a code fence be the
same size.

Found with this hacky perl script:

    foreach my $fn (@ARGV) {
      open(my $fh, '<', $fn);
      my ($fence, $fence_lineno, $prev);
      while (<$fh>) {
        chomp;
        if (/^----+$/) {
          if ($fence_lineno) {
            if ($_ ne $fence) {
              print "$fn:$fence_lineno:mismatched fence: ",
                    length($fence), " != ", length($_), "\n";
            }
            $fence_lineno = undef;
          }
	  # hacky check to avoid title-underlining
          elsif ($prev eq '' || $prev eq '+') {
            $fence = $_;
            $fence_lineno = $.;
          }
        }
        $prev = $_;
      }
    }
