AFAIK, pkg_delete doesn't actually fail, it just prints the message, deletes
everything but the changed files, and that's it.  That's at least how it
works for me with the pine pkg (for which I modify pine.conf).

Problem is, programs can change config file formats as versions change.  A
tag would be good, and I'd rather suggest making the upgrade process move
the files to <filename>.orig, not copy them back.
