issues property
Every problem found while reading the configuration, as a sentence ready to print.
Configuration failures used to be invisible: a file in the wrong shape,
or a key with a typo in it, was read, discarded and replaced by defaults
without a word — the run looked successful and did the opposite of what
the file said. These are what make that audible. lib/ still prints
nothing; bin/ decides whether they are warnings or, under
--strict-config, errors.
