This happens well before any customisation. In fact, it happens before
the lisp engine is started and we enter normal-top-level.

1) Command lines are parsed

2) if no display is required, the terminal is initialised

3) we enter elisp at normal-top-level

4) command-line is called :
     NOW the elisp engine parses the command line and creates a GUI frame
     if necessary, or defaults to using the terminal frame.


Ideally, this could all be fixed after 4, unfortunaltely the terminal is 
already uninitialised/intialised at 2, so even if we make display
failure non-fatal at 4, the terminal/frames aren't in the right state
for us to use anyway.

I worked around this by inserting the kludge at 1.5.

It would require much more major surgery to make this subject to 
customisation, it's all quite deep down inside emacs.
