No, I don't think so. This isn't intentional.
Phillip, please place a breakpoint on `init_display_interactive' in
src/dispnew.c. Then, step to this piece of code:
if (! inhibit_window_system && ! display_arg)
{
char *display;
display = getenv ("DISPLAY");
display_arg = (display != 0 && *display != 0); <----------
if (display_arg && !x_display_ok (display))
{
fprintf (stderr, "Display %s unavailable, simulating -nw\n",
display);
inhibit_window_system = 1;
}
}
and show:
(gdb) p display
Thanks.
