Usability suggestion : completion for M-:

[paul r]

Hello,

Emacs seems to have a consistent behaviour regarding TAB and
completion, i.e : Almost everywhere, TAB triggers completion when :
- indentation does not make sens
- tabulation char is unlikely to make sens

For exemple, TAB triggers completion in find-file. I think TAB should
be bound to lisp-complete-symbol in M-x eval-expression, aka M-: .

Hope everybody agree and this will be widely considered as a simple
yet positive change.
