Both these solutions work with tcsh as login shell. Nice(*).
They don't, however, work with bash as login shell. Neither after 
/usr/bin/login nor after exec -l are the bash login startup scripts 
read. I have no explanation, I am simply observing it.

Thus these solutions might work with Jeremy's ~/.x11run indirection, but 
not directly in an X11 wrapper script.

(*)What I am also observing is that both my primitive .x11run script and 
Cameron's deluxe version are actually working, whereas Peter's elegant 
"exec -l" solution works in a script called from the command line, but 
does not work inside .x11run. There it leads to error messages of the type

No explanation; just observing...
