I think it looks better. I'm following what the Python folks do with
their standard documentation. See the bottom of the Python
documentation page [1].

I don't know.

I think the documentation [2] and the README.txt need to update the
copyright years to reflect the current year.

I don't mean to imply that every source file in the Sage library
should update the copyright year(s). The copyright years on those
source files can stay as is. I'm only suggesting that the copyright
years be updated for the standard documentation and the README.txt.
