Re: patch for Dired second header line info

[Richard Stallman]

    The string `total' is the standard string printed by `ls' so maybe we
    should keep it.  Also what do you think about further compacting
    this line as:

    total files 420/694 space 19646/56456000

That is extremely misleading, since the first is
VISIBLE/IN-DIR and the second is IN-DIR/TOTAL.
In other words, the 694 is analogous to the 19646,
but 694 comes second in a pair, while 19646 comes first in a pair.

    Also we could add a tooltip explaining what these numbers mean if they
    are not obvious.

Using a tooltip to explain could be a good idea, but we
should still try to make it clearer in the text.
There is no shortage of space in that line.
