 Determines a pattern to ignore a buffer name for various things (e.g. the
 tabline extension) or the read-only check. Default is
 `g:airline#extensions#tabline#ignore_bufadd_pat` (see below) or
-`'defx|gundo|undotree|vimfiler|tagbar|nerd_tree|startify|!'` if it is unset.
+`'!|defx|gundo|nerd_tree|startify|tagbar|undotree|vimfiler'` if it is unset.
 
 The "!" prevents terminal buffers to appear in the tabline.
