jmoiron/dotfiles 65dab65 update cm.linux to include new improved diffs & statuses that take into account missing files, and add -r to diff and status to give a 'reverse' status
fb56daf1 to cm darwin diffstat does not have -C option (what a surprise)
66917536 to cm use diffstat to provide a nice status command, change list to behave like show used to, add some diff/diffstat related code cleanup
