if [ -z "${1-}" ]
That looks ugly to me. Any reason we shouldn't just "set +u" at the top of
the script?
As already discussed, because the script must be sourced, then the "set
+u" has global scope.
I suppose that the option could be tested and then reset as appropriate
at the end of the script.
(note: for some reason Mercurial's bash completion script does not have
this problem; they use $1 directly without bash complaining)
