Function declarations in the REPL are preprocessed into variable
declarations before being evaluated. However, the preprocessing logic
did not account for the star in a generator function declaration, which
caused the preprocessor to output invalid syntax in some circumstances.

Instead of writing to the REPL’s input stream for the alignment
spaces in `.editor` mode, let `readline` handle the spaces
properly (echoing them using `_ttyWrite` and adding them to the

In `.editor` mode, `repl.write()` would have crashed when the
`key` argument was not present, because the overwritten
`_ttyWrite` of REPLs doesn’t check for the absence of a second
argument like `readline.write()` does.
Since the docs indicate that the argument is optional, add
a check paralleling the one in `readline.write()`.

In most cases, named functions match the variable or property to which
they are being assigned. That also seems to be the practice in a series
of PRs currently being evaluated that name currently-anonymous
functions.
This change applies that rule to instances in the code base that don't
comply with that practice.
This will be enforceable with a lint rule once we upgrade to ESLint
3.8.0.

When `useGlobal` is false, tab completion in the repl does not enumerate
global properties. Instead of just setting these properties blindly on
the global context, e.g.
context[prop] = global[prop]
Use `Object.defineProperty` and the property descriptor found on
`global` for the new property in `context`.
Also addresses a previously unnoticed issue where `console` is writable
when `useGlobal` is false.
If the binary has been built with `./configure --without-intl` then the

This commit addresses https://github.com/nodejs/node/issues/5431 by
changing the way that the repl handles assignment to the global _
variable.
Prior to this commit, node sets the result of the last expression
evaluated in the repl to `_`. This causes problems for users of
underscore, lodash and other packages where it is common to assign
`_` to the package, e.g. `_ = require('lodash');`.
Changes in this commit now result in the following behavior.
- If unassigned on the repl, `_` continues to refer to the last
evaluated expression.
- If assigned, the default behavior of assigning `_` to the last
evaluated expression is disabled, and `_` now references whatever
value was explicitly set. A warning is issued on the repl -
'expression assignment to _ now disabled'.
- If `_` is assigned multiple times, the warning is only displayed once.
- When `.clear` is executed in the repl, `_` continues to refer to its
most recent value, whatever that is (this is per existing behavior).
If `_` had been explicitly set prior to `.clear` it will not change
again with the evaluation of the next expression.
