[ruby/irb] Add OMIT_ON_ASSIGNMENT
Omit the results evaluated at assignment if they are too long. The behavior of ECHO_ON_ASSIGNMENT being on by default is hard to understand, so I change it to off by default. Instead, we turn OMIT_ON_ASSIGNMENT on by default. The result is displayed on assignment, but it will always be short and within one line of the screen. https://github.com/ruby/irb/commit/c5ea79d5ce
