I don't see what that code snipit has to do with the script (but I am
in the camp that would go ahead and waste the four bytes of source
code to write that as (strcmp(a, b) == 0)).
I _did_ write the original script the way I was thinking/would say it,
"If $kldxref_module_path is empty, use the sysctl(8), otherwise, use
its contents."
I guess I was thinking of '-z' as a positive, "is empty," rather than
a negative, "is not filled."
But whatever. I've changed it to the "positive" in my repository. I'll
commit the latest version later and everyone can make there own
fixes/additions/changes/PRs.
