When no -E is supplied, we always default to SQL_ASCII; there's no
possibility of adopting a value from the environment.  The reason that
the locale printout exists is that the command line doesn't completely
specify what locale will be used.  That reason doesn't apply to encoding.

No they won't.  They will likely not even notice this message in the sea
of other messages they've never seen before; and even if they do notice
it, they will certainly not realize that they don't want it.  If the
message were to *say* "this is probably a bad choice because it's
incompatible with your locale selection", then it might possibly have
the effect you're hoping for, but I don't see how we can find that out.

We could make initdb print out every other setting it has too, but that
would not improve its user interface.  Adding messages that don't carry
useful content just debases the importance of each one.
