Re: libexecdir/datadir used incorrectly

[Karl Berry]

    | This should normally be @file{/usr/local/sbin}, but write it as
    | @file{$(exec_prefix)/sbin}.  (If you are using Autoconf, write it as
    | @samp{@@sbindir@@}.)

Sorry, but once again, I fail to see any meaningful difference between
this text and the text that's already there.  I don't object to it, but
I don't see the point.  It mentions the actual directory name, but so
what?  I don't get it.

Whereas Alexandre's text actually gives an additional explanation to the
situation, so it makes sense to me.  It doesn't change the meaning and
seems perfectly clear to me.  I don't understand your objection to it.

    datadir := $(datadir)/package-name

This would be inane.  We can't possibly specify against every crazy
thing people can do.  I wouldn't even want to mention it -- seeing the
wrong example will give people ideas.
