I prefer to throw an error because looks familiar compared with
what i see when using GNU/ls.
If i try:
C-x d ~/emacs-master/lisp/*.Z RET

I) with GNU/ls or with ls-lisp:
i get an error and i read in the echo area:
Reading directory: No such file or directory, ~/emacs-master/lisp/*Z

II) with eshell-ls:
I actualy get a Dired buffer with an entry (the directory itself).

I rather prefer if II) behaves as I) regardless on 
'eshell-error-if-no-glob', that means, my second patch with the 
user-error.
