Probably sensible.

I think it'd be better for this to be "set autolist=ambiguous" - it
changes an accidental keypress into a deliberate choice, and matches
Linux a bit better.

I always override the prompt anyway.  My personal favourite is
set prompt="%B%n@`hostname -s`%b:%/ %h% "
but I see no real problem with the suggested prompt (although
set prompt = "%n@%m:%c04%# " 
would at least save one character.
