 You have
 {{{
             if (ref $input_file->{target} eq 'ARRAY') {
                 $input_file->{target} = process_template_opt($project,
                                             $input_file->{target},
 $options);
             } else {
                 $input_file->{target} = $config->{run}{target};
             }
             if (ref $input_file->{target_prepend} eq 'ARRAY') {
                 $input_file->{target} = [ @{
 process_template_opt($project,
 $input_file->{target_prepend},
                                                $options) },
                                           @{$input_file->{target}} ];
             }
             if (ref $input_file->{target_append} eq 'ARRAY') {
                 $input_file->{target} = [ @{$input_file->{target}},
                                           @{
 process_template_opt($project,
 $input_file->{target_append},
                                                $options) } ];
             }
 }}}
 below the patch. Two questions:

 1) Do we still need all the array checks in that one given that we already
 checked for arrays in the patch and exit with an error in case the
 condition is not met?

 2) How would the `else` clause still be called given that we are now
 bailing out earlier if `target` is no array?
