Subject: Preserve any existing +INSTALLED_INFO file from an installed package
 before replacing it, and restore it when the new package is installed. This
 saves any state information that should be carried over to the new package,
 e.g. automatic=yes.

XXX Still need to do the same when "un-replacing".
