    PR bin/55468

    Fix crash due to out-of-bounds access with Ctrl-W.

    PR is only for nottywerase, but also fix ttywerase case, taken from
    OpenBSD via nvi2:

    http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/vi/vi/v_txt.c#rev1.23
    https://github.com/lichray/nvi2/commit/5d5365d3585f45651f9b4a366391798a91393337

    Also, comment there is no worry for altwerase specific code, which
    seems suspicious at a glance.

    Reported by Azuma OKAMOTO.
    Thanks for detailed explanation how to reproduce the problem!
