We had mainly been concerned with package system artifacts such as
.rpmsave files.  However, editors and filesystems are also a possible
source of unintended duplicates.  I think it might be good to ignore
filenames beginning with ".", as these prefix-form name variants tend to
begin with "." so that they don't show up in ordinary directory listings.
