You have to admit that this is a /bad/ script.  Even if the writer
intended that behavior falling back to using ".", it would have been
better to explicitly ask for it:

  $ test "$var" \
      && find "$var" \
      || find '.'

or at least document that it is using a glitch:

  $ find $var   # Use $var if set, else use ".".

But the latter would not work for unusual file names, of course.

Have a nice day,
