Subject: [ruby-core:18513] Make irb start a new line on EOF

Other interactive interpreters (namely `python`, `lua`, `psh`, and
SpiderMonkey's `js`) emit a newline before exiting when fed an EOF
(^D). This is a nice feature, as it makes your usual shell prompt
start on its own line rather than appear on the same line as the
interactive interpreter's prompt when you leave by pressing ^D, for
instance. Any reason for irb not to do the same?

I tried to make it behave as I wished, and the attached patch is the
trivial solution I found. I should note, though, that I'm not
familiarized with irb's source code, and this was a very quick hack;
maybe this isn't the best place to implement the changes then.

The patch is for the ruby_1_8_7 branch, by the way; on Ruby 1.9, it
seems to be one line off.
