Thomas Shinnick 4cf0ce5bb4 docs: typos and minor edits in several modules
Mostly quite minor edits.  Those possibly of more interest are:

  emitter.setMaxListeners(n)

    That the limit is per event name for an emitter.

  fs.readlink()

    Not a path, but rather the symbolic link's string value, which
      would be at best a partial path, certainly not a 'resolvedPath'

  global.__filename

    This may be "well-known" but this is a full path to the module
    that referencing code is running in.  It is not the main program's
    path, unless you are in the main program.  Each module knows only
    its own path.

  server.listen(port,...)

    I actually needed this functionality... "gimme just _any_ next port"

  stream.end()
  stream.destroy()

    Yeah, everybody knows what happens to the queued data, but let's
    make it *really* explicit for the first readers.

console

For printing to stdout and stderr. Similar to the console object functions provided by most web browsers, here the output is sent to stdout or stderr.

console.log()

Prints to stdout with newline. This function can take multiple arguments in a printf()-like way. Example:

console.log('count: %d', count);

If formating elements are not found in the first string then util.inspect is used on each argument. See util.format() for more infomation.

console.info()

Same as console.log.

console.warn()

console.error()

Same as console.log but prints to stderr.

console.dir(obj)

Uses util.inspect on obj and prints resulting string to stderr.

console.time(label)

Mark a time.

console.timeEnd(label)

Finish timer, record output. Example

console.time('100-elements');
for (var i = 0; i < 100; i++) {
  ;
}
console.timeEnd('100-elements');

console.trace()

Print a stack trace to stderr of the current position.

console.assert()

Same as assert.ok().
