/**
 * Implementation of hook_versioncontrol_alter_repository_selection():
 * Alter the list of repositories that are available for user registration
 * and editing. This hook is called for all users except those with
 * "administer version control systems" permissions.
 *
 * @param $repository_names
 *   The list of repository names as it is shown in the select box
 *   at 'versioncontrol/register'. Array keys are the repository ids,
 *   and array elements are the captions in the select box.
 *   There's two things that can be done with this array:
 *   - Change (amend) the caption, in order to provide more information
 *     for the user. (E.g. note that an application is necessary.)
 *   - Unset any number of array elements. If you do so, the user will not
 *     be able to register a new account for this repository.
 * @param $repositories
 *   A list of repositories (with the repository ids as array keys) that
 *   includes at least all of the repositories that correspond to the
 *   repository ids of the @p $repository_names array.
