I meant that

(defun lisp-indent-line (&optional whole-exp)

takes one optional argument `whole-exp' that implements the feature.

(defun c-indent-line (&optional syntax quiet ignore-point-pos)

takes three completely unrelated arguments and won't implement the
feature.

(defun python-indent-line ()

takes no argument at all and won't implement the feature either.

All this based on the assumption that `indent-for-tab-command' with a
prefix argument would pass something like `whole-exp' down to the
indent-line function of the major mode and have the latter do the job.

Miles elegantly side-stepped the issue in his patch by implementing the
feature within `indent-for-tab-command' so my argument is void.
