I would instead have written something like this: bash-completion: Support running when set -u is enabled Under set -u semenatics it is an error to access undefined variables. Some user environments may enable this in the interactive shell. In any context where the completion functions access an undefined variable, accessing a default empty string (aka "${1-}" instead of "$1") is a reasonable way to code the function, as it silences the undefined variable error while still supplying an empty string.
