   Yes. And a :version on the new defcustom itself.

Right.

   Two spaces after '.'

Good; I prefer that as well.  (I see I chose a poor example as a commit
log message prototype.)

   "Whether `shell-get-old-input-default' includes \"\\\" lines."

Nice; I was wondering how to make that more concise.

       Bob> +(defun shell-get-old-input ()
       Bob> +  . . .
       Bob> +  (let (field-prop bof)

       Bob> +	(field-string-no-properties bof)

   Emacs uses spaces only in elisp. We even have a .dir-locals.el
   enforcing that.

I hadn't noticed that, actually -- either the .dir-locals.el or the
policy.  FWIW, I think both of these tabs are from cutting-and-pasting
from comint.el.
