You want to create a new settings item in the bundle editor (⌘N) and then set the increase/decrease indent patterns in this settings item, and adjust the scope selector for the item to where it should be active, in your case ‘comment.block.documentation.perl’.

Thanks! This was the "missing link". Just for the records: The correct settings for Perls POD sections is

{   increaseIndentPattern = '';
    decreaseIndentPattern = '';
}

The above disables any automatic indention, which in my opinion is the best setting for PODs.

What would be the best way to contribute such changes and settings to the built in Perl bundle?

Thanks again, Ingo
