I don't have `/usr/share/kbd/keymaps/' in my system.
dualbus@debian:~$ ls -l /usr/share/kbd/keymaps/
ls: cannot access '/usr/share/kbd/keymaps/': No such file or directory
>From what I can tell, I get these keymaps by installing `console-data'
in my Debian system, although these are installed under `/usr/share/keymaps/',
and have different extensions (e.g.
`/usr/share/keymaps/i386/qwerty/pc110.kmap.gz')

I think this is an easier way to reproduce the problem. I have a terminal
window with the following dimensions:
dualbus@debian:~$ declare -p COLUMNS LINES
declare -- COLUMNS="191"
declare -- LINES="49"
dualbus@debian:~$ bash --version | head -n1
GNU bash, version 4.4.12(1)-release (x86_64-pc-linux-gnu)
Running the script in `interactive' mode (which triggers calls to
`get_new_window_size' through `get_tty_state' when checkwinsize is
enabled), lays out the options on seven columns:
dualbus@debian:~$ bash -i script
$- himB
cols 191
1) aaaaaaaaaaaaaaaaaaaa 8) aaaaaaaaaaaaaaaaaaaa 15) bbbbbbbbbbbbbbbbbbbb
22) cccccccccccccccccccc 29) dddddddddddddddddddd 36) eeeeeeeeeeeeeeeeeeee
43) ffffffffffffffffffff
2) aaaaaaaaaaaaaaaaaaaa 9) bbbbbbbbbbbbbbbbbbbb 16) bbbbbbbbbbbbbbbbbbbb
23) cccccccccccccccccccc 30) dddddddddddddddddddd 37) eeeeeeeeeeeeeeeeeeee
44) ffffffffffffffffffff
3) aaaaaaaaaaaaaaaaaaaa 10) bbbbbbbbbbbbbbbbbbbb 17) cccccccccccccccccccc
24) cccccccccccccccccccc 31) dddddddddddddddddddd 38) eeeeeeeeeeeeeeeeeeee
45) ffffffffffffffffffff
4) aaaaaaaaaaaaaaaaaaaa 11) bbbbbbbbbbbbbbbbbbbb 18) cccccccccccccccccccc
25) dddddddddddddddddddd 32) dddddddddddddddddddd 39) eeeeeeeeeeeeeeeeeeee
46) ffffffffffffffffffff
5) aaaaaaaaaaaaaaaaaaaa 12) bbbbbbbbbbbbbbbbbbbb 19) cccccccccccccccccccc
26) dddddddddddddddddddd 33) eeeeeeeeeeeeeeeeeeee 40) eeeeeeeeeeeeeeeeeeee
47) ffffffffffffffffffff

7) aaaaaaaaaaaaaaaaaaaa 14) bbbbbbbbbbbbbbbbbbbb 21) cccccccccccccccccccc
28) dddddddddddddddddddd 35) eeeeeeeeeeeeeeeeeeee 42) ffffffffffffffffffff
#? q
Whereas running the same script in `non-interactive' mode results in three
columns.
dualbus@debian:~$ bash script
$- hB
cols 191
1) aaaaaaaaaaaaaaaaaaaa 17) cccccccccccccccccccc 33) eeeeeeeeeeeeeeeeeeee
2) aaaaaaaaaaaaaaaaaaaa 18) cccccccccccccccccccc 34) eeeeeeeeeeeeeeeeeeee
3) aaaaaaaaaaaaaaaaaaaa 19) cccccccccccccccccccc 35) eeeeeeeeeeeeeeeeeeee
4) aaaaaaaaaaaaaaaaaaaa 20) cccccccccccccccccccc 36) eeeeeeeeeeeeeeeeeeee
5) aaaaaaaaaaaaaaaaaaaa 21) cccccccccccccccccccc 37) eeeeeeeeeeeeeeeeeeee
6) aaaaaaaaaaaaaaaaaaaa 22) cccccccccccccccccccc 38) eeeeeeeeeeeeeeeeeeee
7) aaaaaaaaaaaaaaaaaaaa 23) cccccccccccccccccccc 39) eeeeeeeeeeeeeeeeeeee
8) aaaaaaaaaaaaaaaaaaaa 24) cccccccccccccccccccc 40) eeeeeeeeeeeeeeeeeeee
9) bbbbbbbbbbbbbbbbbbbb 25) dddddddddddddddddddd 41) ffffffffffffffffffff
10) bbbbbbbbbbbbbbbbbbbb 26) dddddddddddddddddddd 42) ffffffffffffffffffff
11) bbbbbbbbbbbbbbbbbbbb 27) dddddddddddddddddddd 43) ffffffffffffffffffff
12) bbbbbbbbbbbbbbbbbbbb 28) dddddddddddddddddddd 44) ffffffffffffffffffff

14) bbbbbbbbbbbbbbbbbbbb 30) dddddddddddddddddddd 46) ffffffffffffffffffff
15) bbbbbbbbbbbbbbbbbbbb 31) dddddddddddddddddddd 47) ffffffffffffffffffff
16) bbbbbbbbbbbbbbbbbbbb 32) dddddddddddddddddddd 48) ffffffffffffffffffff

AFAICT, this is intentional. There's another option though. If you read
https://lists.gnu.org/archive/html/help-bash/2015-03/msg00005.html, you'll see
why the following works:
# seven columns, non-interactive
dualbus@debian:~$ bash script

For some reason though, the following fails to update the value of COLUMNS:
dualbus@debian:~$ cat script
#!/bin/bash
shopt -s checkwinsize
options=(
aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaa

ffffffffffffffffffff ffffffffffffffffffff
)
echo \$- $-
echo cols $(tput cols)
command true # this should trigger?
select opt in "${options[@]}"; do
break
done
So the trick is to run an external command in foreground. To see why this
works, read:
