Its not on by default; M-x 'column-number-mode' should enable it. I don't actually know if it always treats tabs as 8 columns, or if there's some magic variable controlling how it treats tabs. Given it's emacs, probably the latter. Fwiw, I don't usually use vi, but I had a quick poke in vim and it seems to show both tab-unexpanded and tab-expanded numbers for the columns (when pressing ^G, anyway). > I make a macro that moves > forward one space, and run that macro, eg 28 times, which ends up in the > wrong place.
