I haven't looked at it (and don't have time at this exact moment) but
I imagine it's something like this: Keep track of how deep you are
nested within the [['s, and treat the | characters differently
according to context. If you're at the top level, a | character is a
delimiter for that level, but if you're already nested inside another
[[ level (i.e. you're inside a link) then treat the | character
according to the piped-link interpretation. Look for ]]'s to know
when you should pop back out to the previous level/context.
