Ben, I believe one of your changes to kill-line broke its execution in
macros.
For some time now I've been witnessing a strange discrepancy in the
behavior of keyboard macros during recording and execution. Finally
I've narrowed it down to `kill-line' misbehaving. The problem is that
the variable `kill-whole-line' is not respected when `kill-line' is
executed as part of a keyboard macro.
TO REPEAT:
Start `xemacs -vanilla', set `kill-whole-line' to t. See that
kill-line at BOL kills the entire line. Now record a macro solely
consisting of C-k:
C-x ( C-k C-x )
Try executing it with `C-x e' and you'll see that it no longer kills
the whole line, but only the part up to the newline, as if
kill-whole-line were set to nil.
I haven't had the time to investigate this properly, but I suspect the
problem is in this change:
If called interactively, may kill the entire line when given no
^^^^^^^^^^^^^^^^^^^^^^^
argument at the beginning of a line; see `kill-whole-line'.
Apparently functions bound to keys executed in keyboard macros get
call non-interactively[1]. In the case of kill-line, it makes a big
difference, thus causing the macro weirdness.
I'm working around the problem by redefining kill-line in my .emacs,
but a real fix would be to make macro execution execute commands with
`call-interactively', as God intended. (But this may cause other side
effects.)

This is easy to test by creating a dummy command that prints a message
if (interactive-p) and binding it to a key. And indeed, I confirmed
that such a command prints its message on a key press, but not when
invoked as part of macro execution!
