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
