Re: /run and needing a --rundir for configure

[Karl Berry]

    This should normally be @samp{$(localstatedir)/run}, but having a
    separate variable allows the user to customize it separately from
    @env{localstatedir}, for example to use @file{/run}.  If you are using
    Autoconf 2.70 or later, write it as @samp{@@rundir@@}.

I wanted to use the wording parallel to the other cases, with extra
text clearly set off.

Sending off to rms, we'll see what happens.

Thanks,
