Remove verbosity for -noverbose; cleanup in code layout and message texts

Remove verbosity for -noverbose; cleanup in code layout and message texts

We shouldn't print information messages if we run non-verbosely.
In this case, the message appeared not to be helpful because it
suggests to re-run the command with `-verbose' ... but sending the
message again is usually not possible, not wanted or would produce
different results.

This is a cleanup of Philipp's patch.
