This is the enhancement to `org-narrow-to-subtree' that I suggested back in May [1]. It allows you to choose what level subtree to narrow to. There are two ways to specify the subtree: use repeated C-u's to select "upward" from the current subtree, or use a direct numeric prefix arg to specify the subtree "downward" from level 1. (This is a somewhat unusual prefix argument usage, but it's useful to be able to choose from either direction, and the convenience of using C-u to select upward is quite enormous -- I expect it to be the common case, and it's pretty much the only way I use the feature.) The prefix arg is optional, of course: if you don't pass it, then `org-narrow-to-subtree' behaves the same way it has always behaved.
