Make --json and --quiet suppress automatic init messages

And any other messages that might be output before a command starts.

Fixes a reversion introduced in version 5.20150727.

During the optparse-applicative conversion, I needed a place to run
per-command global option setters, and I made it get run during the seek stage. But
that is too late to have --json and --quiet disable output produced in the
check stage. Fix is just to run those per-command global option setters at
the same time as the all-command global option setters.
