I think that was just simple proof-of-concept test code to check that awk
was reading the journalctl output stream. Quite reasonable if you've
never user awk before.

I don't recall needing the '--' in the "awk -- 'short awk prog'" command
before, but there seems to have been a bit of rationalisation going on. I
notice that now (Fedora 32) /usr/bin/awk is now a symlink pointing to /
usr/bin/gawk but don't know when that happened or which other distros do
the same.
