syntax errors mess up node REPL history support

[sam-github]

The repl seems to stop understanding the arrow keys for history navigation:

> try{require('/etc/passwd')}catch(e){console.log('e<', e, '>')}

/etc/passwd:1
unction (exports, require, module, __filename, __dirname) { root:x:0:0:root:/r
                                                                    ^
e< [SyntaxError: Unexpected token :] >
undefined
> ^[[A^[[A^[[A

The ^[[A stuff is my up-arrow key, which works usually. This is ubuntu 13.10, fwiw.

Also see #6920, which is exhibited here.

It has nothing to do with REPL, and caused by a tty reset while printing the error.

#6920 is a real issue here
