Recursion should not execute all makefiles found in a project

At the moment, the recurse function looks like this :

 function recurse($path, $directory) {
    $makefiles = drush_scan_directory($this->path . '/' . $directory, '/\.make$/');
    if (!empty($makefiles)) {
      $build_path = $this->base_install_path;
      foreach ($makefiles as $file) {
        $info  = $this->queue->addItem('drush_make_parse_info_file', $file->filename);
        $valid = $this->queue->addItem('drush_make_validate_info_file', array(), $info);
        $this->queue->addItem('drush_make_add_projects', array(TRUE, trim($build_path, '/'), $this->tmp_path, $this->base_path), array($valid));
        $this->queue->addItem('drush_make_add_libraries', array(trim($build_path, '/'), $this->tmp_path, $this->base_path), array($valid));
      }
    }
  }

What this means is that when it downloads an install profile and a module, it will execute ALL the makefiles found in the entire directory tree.

In my mind there should only be one makefile automatically assumed, namely : $projectpath/$project.make

Even though this isn't an issue currently, I ship my drush backend module 'provision' with a makefile that can create the front end, including downloading drupal from a drush command.

This makefile is specifically not called provision.make, but with this code if drush_make had to fetch provision (which is irrelevant at the moment because it isn't a module or hosted on d.o), it would try and fetch an entire drupal directory and store it inside the system.

Another use (other than shipping with a distro makefile), is the option of shipping with light / full makefiles. So if there are optional, but recommended modules you can ship the rules to fetch those alongside your install profile.

Plus, i'm kind of hesitant of shipping with this since the possibility of conflicting makefiles hasn't been explored yet, and this might trigger errors.

This is a pretty simple change to that function, but i wanted to make my intention to change this documented so we can discuss the implications.
