Since I'm wandering in the historical 4.1.5 release, I gave a look at
these.

Indeed, there were (back to 4.1.5) i.rectify in src and i.rectify2 in
src.alpha. In 5.[03] there were a merge between i.rectify and i.rectify2
but it seems that there were some clash: i.rectify2 was due to be
renamed i.rectify, but remained i.rectify2 and there is another
i.rectify3 (with some fixes). 

So i.rectify2 and i.rectify3 are in the sources but only a i.rectify is
present in the binaries, which seems to be i.rectify2 since i.rectify3
is not compiled by default.


For i.points, there were in src: i.points, in src.alpha: i.vpoints and
the resulting i.points3  seem to be a merge between i.points and
i.vpoints. And there is no i.points2

Yes, my head spins too...;)
