Sorry, I haven't been following this thread.  See below.

terminfo is a fork from ncurses -- but I try to keep it sync'ed. 
Recently, I built ncurses-5.3 for cygwin (it's available as a 'test' 
package right now) and while doing so, I resync'ed terminfo to the 
ncurses base.

I did this because the ncurses maintainer finally folded in most of 
Earnie Boyd's original changes for the "cygwin" terminal.  However, he 
did not include all of them.

In my foolishness, I figured that if the upstream maintainer had seen 
Earnie's patches, but opted to leave out a few codes, that he must have 
had a good reason to do so.  So I followed his lead.  (I never noticed a 
problem pre-release, because I do most of my work in an rxvt window; I 
did only minimal testing in a "DOSbox" TERM=cygwin shell.  Sorry. 
[doesn't everybody use rxvt?? <g>] )

I'll try to figure out which parts are missing, and reinstate them -- 
look for a new release (of terminfo-) sometime in the next week.
