Right now this is all in Gem::Commands::UpdateCommand#do_rubygems_update
I'm trying to think of a solution that would make it easy to define
your own, but I've not arrived at one.
Opening the class and defining it ahead of time could cause the rest
of UpdateCommand not to load. Requiring the file first causes lots of
extra stuff you don't want to load.
