I'd suspect that, just like lists and headings, three levels 
would be rare and four levels very very rare.  So, we're really
looking at just:

    >>abc<<           >>abc<<           >>abc<<
    >>>def<<<         1>>def<<          >>1 def<<
    >>>>ghi<<<<       2>>ghi<<          >>2 ghi<<

Also note that the digit values aren't significant here --
they just identify the corresponding start and end markers.
Any of the versions below would produce equivalent output to
the above:

    >>>>abc<<<<       2>>abc<<          >>2 abc<<
    >>>def<<<         1>>def<<          >>1 def<<
    >>ghi<<           >>ghi<<           >>ghi<<

So, it's entirely up to an author as to whether more >'s or
larger numbers are represent outer divs or inner divs -- all
that PmWiki considers is the order in which they're
encountered in the markup.

And, of course, all of these forms could be made available via
recipe.  So realy what we have to decide is which form(s), if any,
we might want to adopt into the core.  Personally I'm okay with
any of the three.
