[Haskell-cafe] [ANN] brittany-0.9.0.0 (on both hackage&stackage)

[lennart spitzner]

- Implement `IndentPolicyLeft`: A layouting setting that disables "hanging
  indentation". This indentation mode may become default in the future.
  Only configurable via config-file for the time being.
- (!) commandline interface is reworked slightly to support multiple
  inputs/outputs (`brittany --write-mode=inplace *.hs`).
  This removes the --input/--output flags.
- Ensure compatibility with stackage
- Change default global config path (old configs are still respected)
- Improve support for per-project config
- Fix several bugs and Improve language extension support

full changelog at https://hackage.haskell.org/package/brittany-0.9.0.0/changelog

brittany was recently added to stackage, and should hopefully be included in
the next LTS release.
