Yes, that would then not confuse things too much when someone expects \e
as that's the last thing they typed.
The main benefit I can see is when you have entered a large query, then a
smaller one (or another \ command), and want to re-run the large query.
Currently you could use the terminal's history and copy/paste it, but if
you edited the query with \e then that doesn't work (or worse if the
terminal doesn't support it, or it's scrolled off the top of the buffer).
