Ahh! Now I understand how to understand this!

It works a bit:

	Its value is
	"/Users/pete/.emacs.d/PDesktop-22/history"
	Local in buffer *shell*; global value is nil

but, since I deleted ~/.tcsh_history I have /no/ history at all ...  
So the history file as set in .emacs and although it exists and  
although I set comint-input-ring-size to a big value is not read. And  
neither written in GNU Emacsen 22.0.50 nor 23.0.0 nor 21.2.


Enough to prepare a bug report?
