* In theory, --start-at FILENAME is simple: Look for a file called

* a user running 'feh --start-at hello.jpg /tmp' will expect feh to start
* at /tmp/hello.jpg, as if they had used
* 'feh --start-at /tmp/hello.jpg /tmp'. Similarly, XDG Desktop files
* may lead to the invocation 'feh --start-at /tmp/hello.jpg .' in /tmp,
* expecting the behaviour of 'feh --start-at ./hello.jpg .'.
*
* Since a good user experience is not about being technically correct, but
* about delivering the expected behaviour, we do some fuzzy matching
* here. In the worst case, this will cause --start-at to start at the
