I've tested this patch. Although I agree that it is an improvement, I'm a 
little at odd with the feature as is:

   psql=> \e
   # select 1...

then:

   psql=> select 1...
   psql-> <prompt>

I cannot move back with readline to edit further, I'm stuck there, which 
is strange. I would prefer a simpler:

   psql=> select 1...<prompt>

that would also be readline-aware, so that I know I'm there and ready to 
nl but also to edit directly if I want that.

That would suggest to remove the ending newline rather than appending it, 
and possibly to discuss a little bit with readline as well so that the 
display line is also the current line for its point of view, so that it 
can be edited further?
