I can't remember this, so I apologize if my suggestion has been
discussed many times.
Here is my own choice of behaviour for TAB key :
 - unless point is at the end of line, indent-according-to-mode
 - if point is at EOL :
   - unless line is indented according to mode, indent according to mode
   - if line is indented according to mode, complete

Classic use case would be : I'm typing a line, I start a new line,
type some code, hit TAB to have my line properly indented, carry on
typing, hit tab again to complete my symbol.

I've been using it for 3 years now, and I still like this behaviour a lot.
