I propose to keep the deprecated ones in a separate file. It is easy
to merge if wished.

Attached is a startfile "nad/epsg-deprecated" together with a
corresponding patch for README. This would at least
explain the situation for others. Maybe eventually someone finds
the time to complete the file systematically.
