Title: Adding line numbers to the output of mirb.

Before:

> "hi"
hi
> d
(mirb):1: undefined method 'd' for main (NoMethodError)
> d
(mirb):1: undefined method 'd' for main (NoMethodError)
> "hi"
hi
> "#{'}"
line 1: unterminated string meets end of file

After

> "hi"
hi
> d
(mirb):2: undefined method 'd' for main (NoMethodError)
> d
(mirb):3: undefined method 'd' for main (NoMethodError)
> "hi"
hi
> "#{'}"
line 5: unterminated string meets end of file
