bug#32659: SES cursor control

[Bill Daly <dalyw@dalywebandedit.com>]

SES cusor control is not working.  When viewing a spreadsheet the cursor
movement keys should move from cell to cell.

The up and down keys seem to work but the left to right keys move the
cursor character by character.

I recently upgraded to:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS
Release:        18.04
Codename:       bionic

This behavior surfaced after the upgrade. Emacs version installed by ubuntu:

/usr/bin/emacs --version

I downloaded the source code for 26.1, compiled and installed to
/usr/local. SES coninued to misbehave.

I Downloaded 25.3; compiled and executed emacs from the src
directory. SES still not right.

I went to my laptop, (Ubuntu 16.04 codename xenial) and noted first the
SES works and second emacs version 24.5.1.

Back at my desktop, I downloads 24.5; the compilation failed and I gave
up.
