Hmm. I definitely recall otherwise.

The old Unix definition is that the empty string stands for "."
so that 'ls ""' means the same as 'ls .'
and 'ls /tmp/""' the same as 'ls /tmp/.'.

Let me try.

On a recent Linux system:

% ls -l ""
ls: cannot access : No such file or directory

On an old Unix system:

# ls -l ""
drwxr-xr-x  2 bin      1040 Jan  1  1970 bin
drwxr-xr-x  2 bin       352 Jan  1  1970 dev
drwxr-xr-x  2 bin       304 Aug 20 12:39 etc
