The term/*-win.el files are preloaded in Emacs 23 on the platforms they 
are appropriate for.
So they are certainly loaded before the user's init file.

Is this something you have actually seen happening, or are you 
extrapolating based on your assumption above?

These sound problematic, as does 3 (not quoted). S-mouse-1 is bound to 
the buffer font menu on other platforms, and we don't generally bind 
keys with the super modifier, but if they are bound to functions that 
the user would expect on nextstep derived platforms, then that might be 
OK. However, binding anything to a power-off command within Emacs sounds 
like a bad idea.
