Comment:

 There are a few small formatting issues, and it would be good to add an
 example showing that {{{arg(sqrt(2)+i)}}} remaining symbolic (as opposed
 to `arctan(1/sqrt(2))`) still evaluates correctly numerically.  Otherwise
 looks fine.  Currently running tests, as `arg` is likely used in a ''lot''
 of places in Sage...
