new.packages() reports on packages which are installed as well as not installed,
for packages installed using install.packages() and the argument
installWithVers=TRUE

This contrasts with reporting only on uninstalled packages (correct behavior)
for packages installed using install.packages() and the argument
installWithVers=FALSE.

i.e. 

install.packages(new.packages(),installWithVers=TRUE)   run again and again will
keep installing the same packages.

install.packages(new.packages())  run again and again will only install the
packages once.
