ref: [Bug #4352]
Reline is a readline stdlib compatible library. It also supports
multiline input. IRB is improved with Reline and supports multiline.
Besides, supports showing documents when completed.

There was incorrect backticks (`) instead of plus signs to denote method
references, and a typo.

For some reason this very useful method was undocumented since it was added in
493e488974 which makes finding it in the docs
impossible before this change.
I've added a detailed example with sample code because it's one of the most
powerful tools to debug Ruby code and I believe very few people are aware of it
due to the lack of documentation.

* lib/irb.rb (eval_input): restore the last error `$!`, as the
previous result. [Feature #14684]
* lib/irb/context.rb (evaluate): add `exception` keyword argument
to set the last error.

if stdout is not a tty.

This is not perfectly good solution (at least we don't want to have ARGV
as default value of `argv` argument), but unfortunately IRB.setup and
IRB.parse_opts are public methods and we can't make breaking change to
those methods.
We may deprecate using them and then make them private in the future,
but the removal should not be in Ruby 2.5. So I kept their interface for
now.
