64fc5a4541 Revert "Revert "repl: disable Ctrl+C support..."
Full original message:

  Revert "repl: disable Ctrl+C support on win32 for now"

The original fix was a stop gap until a libuv update landed.
As the libuv update has not yet landed on v6.x the revert should
not have landed. This commit reverts 1d400ea484 reapplying the
stopgap fix until we update libuv.

ed3de0854e repl: make key of repl.write() optional always
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()`.

7b75cb9e5a test,lib,benchmark: match function names
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.

c39f6c0204 repl: Enable tab completion for global properties
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
`Intl` builtin type will not be available in a repl runtime. Check for
this in the test.

ad8257fa5b repl: Assignment of _ allowed with warning
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.

40d57b714e repl: fix stack trace column number in strict mode
On strict mode, "'use strict'; void 0; " is added as prefix
in order to prevent "use strict" as the result value
for let/const statements. It causes wrong column number in
stack trace.

ee7754be47 repl: accept no arguments to start()
Currently, there is a check to ensure that the user either
provides an object or a string to repl.start(). The string case
is used to set a REPL prompt. However, a default of '> ' already
exists, so forcing the user to specify a prompt is a bit
redundant. This commit removes this restriction.

a06066ca31 repl: allow multiline function call
Currently, the repl allows multiline function declarations, strings, and
all sorts of niceties by catching the SyntaxErrors they issue and
ignoring them. However, the SyntaxError raised by multiline function
calls was not caught. This commit adds to the whitelist.
