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.
