There's no need to change this, since as noted in the comments in
terminfo.src, it does not correspond to any terminal type that is valid
for Debian.
Which comments?
I was thinking of

But there's no such terminal.
I'm a bit confused really; the xterm-r6 definition in misc/terminfo.src
has kdch1=\E[3~. The xterm-r6 definition in debian/xterm.ti has
kdch1=\177, and I'm pretty sure we get that from the xterm source
distribution... I wonder why they diverged?
I'm not 100% sure, since some of the changes are old. I see looking at
xterm's terminfo history that kdch1 was originally \E[3~. In August 1996,
there's a change to make it \177. I don't see that in any of my patches
(though I did make other changes to the terminfo around then - added the
ech string).
The XFree86 CVS only shows "updates" for the change comment on that file.
So who and why the change was made - I doubt that the answer is
forthcoming. I don't see any xterm-fixes for that period in XFree86's
changelog other than mine, and doubt that David Dawes recalls who
submitted the change.
ncurses's terminfo is maintained separately, and I probably ignored this
since when I compare the two, I'm focused on the XFree86 flavor -
xterm-r6 and xterm-r5 are in xterm's file just for convenience.
If I noticed it before, probably regarded it as confusion between kbs and
kdch1 (as for example my fixes for xterm patch #124).
