remove \ ->

[lue-bird]

For example, when one moves an argument from a lambda to the declaration level, some \ -> might remain.
These have to be removed manually, while elm-format could remove those empty lambda arguments patterns automatically.

@lue-bird can you provide a sample Elm code with the before/after how it should look? I might have time to try and fix this 😄

-description content = \ -> Ui.text content
+description content = Ui.text content

-|> List.map (\-> Ui.text)
+|> List.map Ui.text

Or are you looking for situations where one might remove lambda arguments?
