bug#3435: 23.0.91; Two-column mode don't split columns correctly

[Teemu Likonen]

In two-column mode there is "2C-split" (C-x 6 s) command which is
supposed to detect the split column and then split window vertically
etc. The column detection does not work correctly in my Emacs 23.0.91.1.

Example file:

    foo  123
    bar  456

Put the point before the "1" and try the 2C-split command (C-x 6 s). The
left buffer/window contains this:

    foo
    bar  456

And the right buffer/window contains this:

    123

Only the first line is actually split.

There is another minor bug: "2C-dissociate" (C-x 6 d) command does not
update the modeline. It looks like 2C mode is still turned on even
though it isn't. Then "recenter-top-bottom" (C-l) updates the modeline.
