(https://github.com/ruby/irb/pull/869)
Currently, if the signature's constant part is not defined, a NameError
would be raised.
```
irb(main):001> show_source Foo
(eval):1:in `<top (required)>': uninitialized constant Foo (NameError)
Foo
^^^
from (irb):1:in `<main>'
```
This commit fixes the issue and simplifies the `edit` command's implementation.
