Subject: [PATCH] Require RDoc in `input-method.rb` again in a limited scope.

RDoc is implemented as soft dependency in IRB. See how the rdoc is required in
the files. I reverted the commit below.

```
$ grep -ril rdoc lib/
lib/irb/cmd/help.rb
lib/irb/completion.rb
lib/irb/easter-egg.rb
lib/irb/input-method.rb
```
