The input record separator will not help you here, because your input has
no well-defined record separator.


my $curr_key = '';

while (<>) {

  chomp;

  if (/=/) {

    my($key, $value) = split /\s*=\s*/, $_, 2;
    $hash{$key} = $value;
    $curr_key = $key;

  } else {

    $hash{$curr_key} .= " $_";

  }

}
