Hmm. my xterm termcap doesn't have a ti string... looks like vi
and bash, and definitely elvis (another vi-alike i happen to have
source around) all set keypad mode directly using the ks/ke strings.

so for vi/bash/elvis that means either patch sources or the ks/ke strings?
or am i still overlooking something...
