[PATCH xinit 2/2] startx: Make startx auto display select work with per user /tmp dirs

Hi,

That's not true actually. The xauth file can have a display wildcard, but
the xauth command doesn't support generating xauth files with display
wildcards.

Yea, exactly!  I would go a step further and just always do what the
-autodisplayconfig line does, implicitly. Of course, if the caller passes
in a -auth line and $DISPLAY, use the ones passed in, but always do
-displayfd no matter what, since -displayfd works fine with a passed
in $DISPLAY and is still useful for getting ready notification without
having to use unix signal handlers.
