Reinstate an alternate incarnation of r25822, *really* fixing administrative property file handling for prop changes to a file which is subsequently copied/moved over another schedule-delete file, where the original doesn't have any props (e.g. 'svn mv a b; svn ps name val b; svn mv b a' is a 1.5-specific way to trigger this problem).
Reinstate an alternate incarnation of r25822, *really* fixing
administrative property file handling for prop changes to a file which
is subsequently copied/moved over another schedule-delete file, where

b; svn mv b a' is a 1.5-specific way to trigger this problem).

* subversion/libsvn_wc/update_editor.c
  (svn_wc_add_repos_file2): For schedule-delete files that have no
   (destination) base properties file, create an empty base props file
   with a temporary name.
