Re: C-u prefix behavior of TAB broken

[Richard Stallman]

    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.

Nonetheless, C-u TAB seems to work correctly in C mode.  Whatever
differences there may be in the structure of the code in C mode, this
feature works, and it should continue to work.
