O_EDGE_INSERT_STAY
- When inserting into a field up to the boundary position, option-
- ally delay the scrolling, so that the last inserted character
- remains visible, but advance the cursor to reflect the insertion.
- This allows the form library to display the inserted character in
- one-character fields as well as allowing the library to maintain
- consistent state.
