Subject: [PATCH] tests: set `$COLUMNS` when running CLI tests

As reported in #4394, at least `test_show_command::test_show_basic`
can fail when run with a narrow terminal. This patch sets
`COLUMNS=100` in the environment when running tests so the CLI uses
that value instead of using the width of the user's terminal.
