What's so hard about [ -D ] before the datadir argument?

I'm sorry to have given you the impression that I objected to it because
it was hard. Since I proposed the same thing a few lines after what you
quoted, I guess I have to agree it's not hard.

I think it's pointless, because if you're going to look at the usage
message to begin with, why not do what it already says? But I don't
care enough to argue about it any further.

There's also the reverse situation: you see that a script contains a line like "pg_controldata -D foo". You're accustomed to doing just "pg_controldata foo", and you wonder what the -D option does. So you look it up in the docs or "pg_controldata --help".
