Currently this sniff will not report undefined variables which are passed as arguments to certain functions that are designed to assign those variables a value by reference. For example,
preg_match('foo', $bar)will not report$baras undefined.This PR adds documentation and better tests for the
sitePassByRefFunctionsoption that already existed but was undocumented. That option allows adding custom functions to the list of pass-by-reference functions.Inspired by #67 (see also #69)
