bug#23263: cat: missingfile: No such file or directory

[Jonny Grant]

Hello

I noticed that cat doesn't have an accurate message in the following 
use-case:

$ cat missingfile
cat: missingfile: No such file or directory
$ mkdir testdir
$ cat testdir
cat: testdir: Is a directory

I wrote up the details of the ENOENT problem here:

Please keep my email address in any replies as I am not on this mailing 
list.

Cheers, Jonny
