Right.
It is common editors leave backup files behind when editing files in
place. These files are suffixed with a '~'. Example:
-rw-r--r-- 1 root root 759 May 18 18:58 /etc/default/locale
-rw-r--r-- 1 root root 726 Nov 24 2008 /etc/default/locale~
/etc/default/locale~ is such a file.
Obviously, one does not want to source such files.
The 'case' statement above is there to skip such files.
Other examples of files one wants to avoid are the ones with 'dpkg-dist'
or 'dpkg-old' extensions.
