The parameter parser specifically looked for the old bracket syntax.
This generated a lot of warnings when building the docs. Those warnings
have been fixed by changing the parsing logic.

Documentation incorrectly used bracket notation for optional parameters.
This caused inconsistencies in usage because of examples like the
following:

    fs.write(fd, data[, position[, encoding]], callback)

This simply fixes all uses of bracket notation in documentation.

The documentation for http.request and https.request states that
`hostname` is preferred over `host` so the code examples should
use that option name.
