The way I read that is: If I don't specify any -T option, it should
use 'bbox', which 'usually gives whitespace above and to the left...'
But that's not what happens for me. It does not include the DVI origin
(1in to left, 1in up) by default.
Right now it seems that the default is 'tight' instead of 'bbox' - or
maybe I am just parsing this wrong somehow.

I think I understand - I actually don't even want that whitespace, I
just wanted to check that my scripts weren't making use of a bug that
would maybe change in the future (:

No worries, thanks for clearing it up
