On CI systems, you only have the logs written in batch mode. The more
complete they are, the better, since you can always filter out
information you don't need later, but not add missing information
after the fact. So printing lots of information is fine IMO.
A middle ground would be to support some kind of 'verbosity'
command-line option so that the environment could decide how much to
print.
