Subject: 1) clu dbscan test passes file type option(s) (-e -- entry file, -i
 -- index file, -c -- changelog file) for any type of files, which could
 sometimes crashes the command.  To prevent it, introduced a simple file type
 checker and reset the file type if it does not match the real type. 2) key
 search was not working when the key has multiple values.
