obs-service-docker_label_helper-0.0-160000.3.2

- Support Docker.FLAVOR in _multibuild (boo#1225985)

- Handle LABEL statements with any whitespace
- Handle LABEL values containing "=" properly

- Do not ever use "%setup -n .": rpm 4.18 tries to be cleaner and
  remove stuff it extraced, which would lead to 'rm -rf .', which
  rm does not like. Use "%setup -c" instead, which creates the
  appropriate %{name}-%{version} directory expected.

- Avoid mangling whitespace by using gsub instead of assigning to
  fields

- Improve summary, description and README.md a bit
- Mention bsc#1193429 in this changelog

- Improve regexp instead of having two as proposed by Fabian Vogt

- Retain compatibility with old syntax. Update documentation.

- Use entry/exit point to determine whether labels should be expanded.
  Doing so makes the Dockerfile compatible with standard
  docker build command.

- Add documentation and a test

- Initial commit
