There is nothing necessarily changed when the user hits the enter
key. I can go into an empty and hit the enter key without modifying
anything, and I'll still get an ::activate signal.

The idea of the activate signal is "The user says do something with
this entry", that's all.

(Randomg sidenote, "activate" also exists for GtkText widgets -
 currently bound to Ctrl-Enter.)
