GA27-2742  for the second quote.

Entry Assist is all or nothing; if it's on then Ins mode causes inserted text 
to replace the blanks without shifting the non-blank text to the right. I don't 
recall whether it leaves a separating blank.

Clear enough.  Thanks.  Citation needed.

So Rob's terminal is nonconforming.  But if that's the modal behavior
among current emulators, it avails suppliers little to count on the
"standard" behavior.  Is it optional?

All blanks?  Trailing blanks?  Respect column alignment like ISPF Edit Change?
