Remove the 'you shall not connect' message from this signal.
While it is a keybinding signal, using it from applications is
fine and, in fact, expected.
* GtkEntry::activate:
* @entry: The entry on which the signal is emitted
*
- * A <link linkend="keybinding-signals">keybinding signal</link>
- * which gets emitted when the user activates the entry.
- *
- * Applications should not connect to it, but may emit it with
- * g_signal_emit_by_name() if they need to control activation
- * programmatically.
+ * The ::activate signal is emitted when the the user hits
+ * the Enter key.
+ *
+ * While this signal is used as a <link linkend="keybinding-signals">keybinding signal</link>,
+ * it is also commonly used by applications to intercept
+ * activation of entries.
*
* The default bindings for this signal are all forms of the Enter key.
