Hm, I see you point. We are actually not using ess-beginning-of-function
in indentation; only in a couple of interactive places where errors are
useful. But I agree that it should comply with the specifications of
beginning-of-defun and beginning-of-defun-function. Derived interactive
functions should handle error messages explicitly.

beginning-of-defun-function was added specifically for swank/slime; so I
fixed it in trunk as you have suggested.
