+The name of the buffer from "out_name" or "err_name" is compared the full name
+of existing buffers, also after expanding the name for the current directory.
+E.g., when a buffer was created with ":edit somename" and the buffer name is

+If there is no matching buffer a new buffer is created.  Use an empty name to

 For a new buffer 'buftype' is set to "nofile" and 'bufhidden' to "hide".  If
 you prefer other settings, create the buffer first and pass the buffer number.
