Bug#2291: missing terminfo capabilities for xterm

[Bill Mitchell <mitchell@mdd.comm.mot.com>]

PACKAGE: ncurses-runtime
VERSION: 1.9.7a-1

The xterm terminfo capability entry seems to have problems.
This presently renders the ae editor nonfunctional in an
xterm (and, I'd guess, gives dftp problems in an xterm as
well.  I noticed that dftp uses ae as a dropout editor).

This uncovered some problems in ae, which I'm addressing
separately.

Testing with xterm from xbase-3.1.2-6, I get \E[e for the
END key, but the terminfo entry has kend=\E[[.

Also, the terminfo entry has no capability defined for
the DEL key.  Testing, I get ^? when the END key is pressed.

Also, the terminfo entry has no capability definitions for
kf13 through kf20 (shifted f3 thru shifted f10).  Testing,
I get the following for these:

    kf13=\E[25~, kf14=\E[26~, kf15=\E28~, kf16=\E29~,
    kf17=\E[31~, kf18=\E[32~, kf19=\E33~, kf20=\E34~
