Specifying Logger.new shift_age option default

[spacemunkay]

http://ruby-doc.org/stdlib-2.3.0/libdoc/logger/rdoc/Logger.html#new-method

From only looking at the docs, it's not obvious what the default value is for shift_age, nor what value disables the option. The only way to find out is to look at the code itself.

Can submit a PR with the following adjustment: trunk...spacemunkay:specify-logger-shift-age-default
