The inner block *might* have been indented properly by perltidy, but when it was done using tabs, it gets lost in the the cut-n-paste.

I am not starting a discussin about leading whitespace here. I personally do not care at all, as long as it looks correct in my editor, you can mix tabs and spaces for my care. I more care about consistency and correct indentation (which seldom happens according to my own rules :P).

Ah, good point, you are correct there is a mix of tabs and spaces in the original. But the innermost print appears to not be indented enough, so my comment still stands ;-)
