no-useless-parameters

|
=====================
|
|
|
|
Reject common XPCOM methods called with useless optional parameters (eg.
|
|
``Services.io.newURI(url, null, null)``, or non-existent parameters (eg.
|
|
``Services.obs.removeObserver(name, observer, false)``).
|
|
|
|
This option can be autofixed (``--fix``).
