R-devel from rsync 04/23

But it also happens in 1.9.0 (always worth checking the current release, 
surely?)

Try CRAN.packages()[121,]

The CRAN PACKAGES file contains

Package: haplo.score

  Linkage Phase is Ambiguous.

 .  R version translation by Gregory R. Warnes

....

and that blank line should not be there.  There are a two others:

Package:        lars

So, something has changed at CRAN, near midnight BST.

I see something new and unexpected here.
