Globbing problems? See shellcheck

[LinuxOnTheDesktop]

The shellcheck program (available for editors and also online at https://www.shellcheck.net/) is unhappy with various parts of the main script (viz., covid19-cli.sh). Many of those problems have to do with 'globbing' and I wonder whether here we have the source of #15.
