These notations largely serve to direct consumers (of both the source and the parsed code reference) to extended information on individual and related conditional tags throughout WordPress. The changeset also standardizes corresponding DocBlock summaries to use third-person singular verbs. Notations have been added for the following functions: * comments_open() * email exists() * has_excerpt() * has_post_thumbnail() * has_tag() * in_category() * in_the_loop() * is_404() * is_active_sidebar() * is_active_widget() * is_admin() * is_admin_bar_showing() * is_archive() * is_attachment() * is_author() * is_blog_installed() * is_category() * is_comments_popup() * is_date() * is_day() * is_dynamic_sidebar() * is_feed() * is_front_page() * is_home() * is_local_attachment() * is_main_query * is_month() * is_multi_author * is_new_day() * is_page() * is_page_template() * is_paged() * is_plugin_active() * is_plugin_active_for_network() * is_plugin_inactive() * is_plugin_page() * is_post_type_archive() * is_preview() * is_rtl() * is_search() * is_single() * is_singular() * is_sticky() * is_tag() * is_tax() * is_taxonomy_hierarchical() * is_time() * is_trackback() * is_user_logged_in() * is_year() * pings_open() * post_type_exists() * taxonomy_exists() * term_exists() * username exists() * wp_attachment_is_image() * wp_script_is() Merges [42710] to the 5.0 branch.
