dojo, drum: give tab completion as true output
This stops slogging the tab completion and intead adds a +sole-effect
for tab completion output.  This is morally correct, and it lets dojo
clients show tab completions how they want.  For example, web dojo could
implement this as a drop-down box.

Another advantage is that this puts the rendering logic in drum, which
knows the width of the terminal.  Thus, we can make sure each match
takes no more than one line by truncating with ellipses.  If there's
only one match and it's already fully typed, then we display the whole
type.
