Yes, the current CRAN status of the package is appended just FYI / for 
comparison.

These appended check results in the Debian pre-test output regularly 
confuse package developers. I am suggesting (to R-core) to simply add 
more empty lines before "current CRAN status" and maybe it should also 
say something like "(for comparison)" to clarify that these results are 
not the reason for the failure of the automatic pretest.
