evil-escape sends duplicate/invalid key presses in some console programs

[bcc32]

(Examples with evil-escape-key-sequence set to "fd")

In ansi-term and other term-buffers, when running less, if the user
presses f, the file being viewed is actually scrolled down twice
instead of once as it should be.

This is because evil-escape causes an f key press from the user to
be sent as the following sequence of key presses:

f <backspace> f

In general, term-mode can be running some arbitrary program that
doesn't interpret f <backspace> f as equivalent to f. In that
case, it doesn't seem like evil-escape is completely safe to use in
term-mode at all, since it's sending key sequences to an arbitrary
terminal program that don't correspond to the user's intention.

Perhaps evil-escape-excluded-major-modes should include term-mode
by default, as evil-escape's support for it works sometimes but is
not correct in all cases.
