I think connecting to the "insert-at-cursor" signal and stopping
emission there if the cursor is in the wrong place would be sufficient
on a GtkEntry.

This would also allow you to allow [little truck] with one space while
disallowing [littlefoo truck], [little footruck], and [littletruck]--
possibilities you can't achieve with just non-editable text alone.

(What are you making?  Sounds neat.)
