Add non-destructive modes to pgindent

Enterprise / PostgreSQL - Andrew Dunstan [dunslane.net] - 23 January 2023 12:09 UTC

This adds two modes of running pgindent, neither of which results in any changes being made to the source code. The --show-diff option shows what changes would have been made, and the --silent-diff option just exits with a status of 2 if any changes would be made. The second of these is intended for scripting use in places such as git hooks.

Along the way some code cleanup is done, and a --help option is also added.
