Bug #14229: An exception in eval has strange message

Is this intentional?  If so, I'm curious what purpose it is for.

    begin
      eval("raise")
    rescue
      p e.message  #=> "(eval):1:in `<main>'"
    end

This leads to progressive backtrace message:

    $ ./miniruby -e 'eval("raise")'
    Traceback (most recent call last):
            2: from -e:1:in `<main>'
            1: from -e:1:in `eval'
    -e:1:in `eval': (eval):1:in `<main>' (RuntimeError)
                    ^^^^^^^^^^^^^^^^^^^^ HIGHLIGHTED
