Fix issue #1719. (#1726)

MANAGER called PF with function NAME in a variable. BUT PF is NLAMBDA so
didn't eval its argument. Changed to use CL:APPLY*. Moved the process
function from a local LAMBDA in Manager.DO.COMMAND to a separate named
function. Tweaked prompt strings for the "CopyDef" and "Rename All" item
menu commands.
