you'releft to capture the output of --show-diff and exit 2 if the output isn't empty by yourself. 

I wonder if we should model this around the semantics of git diff to keep it
similar to other CI jobs which often use git diff?  git diff --check means "are
there conflicts or issues" which isn't really comparable to here, git diff
--exit-code however is pretty much exactly what this is trying to accomplish.

That would make pgindent --show-diff --exit-code exit with 1 if there were
diffs and 0 if there are no diffs.
