strip: calculate list of extra nodes to save and pass it to changegroupsubset When we remove revision N from the repository, all revisions >= N are affected: either it's a descendant from N and will also be removed, or it's not a descendant of N and will be renumbered. As a consequence, we have to (at least temporarily) remove all filelog and manifest revisions that have a linkrev >= N, readding some of them later. Unfortunately, it's possible to have a revlog with two revisions r1 and r2 such that r1 < r2, but linkrev(r1) > linkrev(r2). If we try to strip revision linkrev(r1) from the repository, we'll also lose revision r2 when we truncate this revlog. We already use changegroupsubset to create a temporary changegroup containing the revisions that have to be restored, but that function is unable to detect that we also wanted to save the r2 in the case above. So we manually calculate these extra nodes and pass it to changegroupsubset. This should fix issue764.
