Re: vi-backward-kill-word

["Jun T." <takimoto-j@kba.biglobe.ne.jp>]

Another minor bug in vi mode.

If you enter a combined char and delete it in vi-insert mode by ctrl-H
(bound to vi-backward-delete-char), then only the base char is deleted.

In this case, vibackwarddeletechar() calls backkill() without setting
CUT_RAW flag. backkill() correclty finds the new zlecs but does not
re-calculate the number of raw chars to be killed (the variable ct).
A possible fix may be the following:
