verbatim: insert the full code sequence when <Alt+Backspace> is pressed 

(This could lead to unwanted behavior when the user wants to enter
a literal escape character (0x1B) while the input is somehow getting
stalled, because then a command keystroke after the M-V <Esc> would
get inserted verbatim too, instead of getting acted upon.  But that
is a small price to pay for getting the correct behavior for both
M-V M-Bsp and M-V M-Enter.)

This fixes https://savannah.gnu.org/bugs/?58909.

Bug existed since version 2.6.3, commit 08c51cfd,
but also occurred erratically beforehand.
