New param in plugin_dir_path

[sebastian.pisula]

New param - path. Function with this param return full path to file. Examples:

<?php
var_dump(plugin_dir_path(__FILE__));
var_dump(plugin_dir_path(__FILE__, 'assets/test.png'));

string(26) "\wp-content\plugins\myplugin/"
string(41) "\wp-content\plugins\myplugin/assets/test.png"

What is the advantage of plugin_dir_path( __FILE__ , 'assets/test.png' ) over simply using plugin_dir_path( __FILE__ ) . 'assets/test.png' )? I don't really see a benefit of using a second param for that when you can simply concatenate the strings on your own. Developers would probably not use it because of back compat. Also, plugin_dir_path() says it returns the path to a directory, not a file.
