The idea is that we ultimately want to be able to import a subset of a
large wiki. In Wikipedia, for example, "show me revisions since N" will
be very large after a few minutes. OTOH, "show me revisions touching the
few pages I'm following" should be fast. And at least, it's O(imported
wiki size), not O(complete wiki size)

Ideally, there could be heuristics like

"show me how many revisions since N"
if (not many) {
    "OK, show me them all in details"
} else {
    "hmm, we'll do it another way, show me revisions touching my pages"
}

but let's not be too ambitious for now: it's a student's project,
completing one week from now, and the goal is to have something clean
and extensible. Bells and whistles will come later ;-).
