FWIW:

In my library ls-lisp+.el I use tooltips and links on
parts of that line, and the text for that line is a
bit different.  E.g.:

 files 1610/1610 space used 116754 available 101631612

There are two parts, with a tooltip each:

1. files 1610/1610
2. space used 116754 available 101631612

Tooltip for #1:
 Files shown / total files in directory [RET, mouse-2: more info]

Tooltip for #2:
 Kbytes used in directory, Kbytes available on disk [RET, mouse-2: more info]

Each part also has a link, which shows *Help* with
the `file-attributes' for the directory in tabular form.
