Fix another annoying feature in mg. When I try to use the keypad to
escape from I-search (I don't know if it's legal, but it works in emacs)
the initial ESC in the sequence is caugth by I-search (which exits), but
not the rest of it which ends up written into the buffer.
This is extra annoying when we don't have undo.
Note that this is better than emacs because the ESC is removed if nothing
indicating a multi-char sequence comes within 300 miliseconds. (Try to ESC
from I-search in emacs and then press 'x').
