No that's incorrect. It isn't that . and .. are forbidden, but they are
reserved: every single directory in Unix file systems have a . and ..
directory entry. So they are legitimate directory names -- they're just not
names you can use for your own files, as they are already in use.

That's one way of looking at things... I'm not sure that the empty string
counts as a file name. Its more of the LACK of a file name.

Besides, that would be ambiguous. Would "/home/steve/" mean my home
directory, or the file "" inside my home directory?
