message: Add potentially helpful settings in readme.
  Feel free to delete them if you think they are not helpful or
  out of place.  But I spent way too much time debugging the font
  rendering, so I can imagine others will face the same issue...

  - `open`: check all open files
  - `project`: check the entire project's files

  +### Other potentially helpful settings
  -- Diagnostics behave strangely with transient commands like `#check`.
  +* Fonts with good unicode support (on Linux): `"editor.fontFamily": "Source Code Pro Medium, DejaVu Sans Mono"`
  +* By default, vscode will complete `then` to `has_bind.and_then` when you press enter. To disable this behavior, set `"editor.acceptSuggestionOnEnter": false`
  +* If you like colored brackets, try out [Bracket Pair Colorizer](https://marketplace.visualstudio.com/items?itemName=CoenraadS.bracket-pair-colorizer).
