The interaction with goal-column is odd. E.g. in *scratch*:
1. M-x fundamental-mode
2. M-: (setq display-line-numbers t)
3. M-x column-number-mode
4. TAB push the text of first line rightward, so that the first `;' is
positioned on `o' in `To' on the second line, which the mode line
indicates is column 8.
5. C-x C-n SPC to set the goal-column to 8.
6. C-n to move down to the second line.
=> Point is now not on the `o' in `To' but on the `e' in `create', four
columns to the right (but still column 8 according to the mode line
indicator). In other words, though the movement correctly preserves
the goal column, visually it appears not to.
The same effect happens when setting line-prefix (as expected, given
what Eli pointed out).
