I don't recall a decision on this. Was there one? The thread seems to have
petered out with no conclusion, unless I missed something.

Reminder: there are two suggested changes: (1) highlight the column number,
(2) indicate the region size. The two are unrelated, but both are here:
http://www.emacswiki.org/cgi-bin/wiki/modeline-posn.el.

I think too that I neglected to point out that the region size indication
(e.g. "30 chars") takes the place in the mode-line of the absolute buffer
size indication (e.g. "of 5.9 k") when the region is active. It does not
replace the relative buffer size indication (e.g. "22%"). It is generally
the same size as the text it replaces.
