The original reason for this change (the failure to capitalize was not
always the case) was apparently the request of some large corporates
(probably law firms) that did not want automatic capitalization at the
beginning of numbered items. Fair enough, but the way this was implemented
resulted in failure to capitalize even after numbers in running text, which
is unexpected and (most of the time) absurd. I guess MS had more complaints
about this than about the previous situation, so they flip-flopped back in
Word 2007.
