 ;; Below that, show a line and column coördinate.  There are special minor modes that will enable or disable this for the default mode line, but i ignore that and put the formatting code here directly.  The docstring for the mode-line-format variable suggests that the column might not be displayed correctly in some situations without enabling the minor mode, but i haven't noticed that yet so i don't bother.  This column number is zero-indexed; a capital c would make it one-indexed.  For now i stick with zero-indexed as that's the emacs default and i'm not sure which is better.  I guess it makes a bit more sense that the first character on a line is labeled "1".
 
 ;; I don't know exactly what the final variable covers, so i keep it here so that if something shows up i know that it gets put here.  Because i have a global mode line in my tab bar, some of the things that would otherwise be here (like the time, battery percentage, and notifications for chat buffers) don't show up.
