node console autocomplete suggestion

[girish3]

After hitting tab, why do I get suggestions(sometimes the same thing twice) when there is only one possible autocomplete suggestion.
for example:-
type 'console.lo' in the node and then hit tab.

It's because the auto-completer follows the prototype chain. What that means is this:

> Object.getOwnPropertyNames(console)
[ '_stdout',
  '_stderr',
  '_times',
  'log',
  'info',
  'warn',
  'error',
  'dir',
  'time',
  'timeEnd',
  'trace',
  'assert',
  'Console' ]
> console.__proto__
{ log: [Function],
  info: [Function],
  warn: [Function],
  error: [Function],
  dir: [Function],
  time: [Function],
  timeEnd: [Function],
  trace: [Function],
  assert: [Function] }

Maybe the auto-completer can filter out methods with the same name from higher up in the prototype chain because they're unreachable anyway. Purely filtering on identity won't work though because console.log !== console.__proto__.log.
