If key ends in "+" the value of the key is appended to previous
values found. If values are string instead of a slice they are
automatically converted to a slice of one string.

Configuration will be loaded from config.yaml and then config.yaml.d/*.(yaml|yml) in
alphanumeric order. The merging is done by just taking the last value of
a key found, so LIFO for keys. Slices are not merged but replaced.

Previously a bool flag would be rendered as --flag false for `flag: false`
which is invalid and results in the opposite of what you'd expect.
