Some arguments of lambda functions are incorrectly highlighted

[dtaskoff]

First arguments of lambda functions, starting with letters, which are part of escape sequences (n, r, t, etc.), are highlighted together with the preceding \ as an escape sequence.
e.g.: (\name -> prettify name) gets highlighted as (\name -> prettify name).

I've a fork for syntax highlighting: andys8/vim-elm-syntax. There are smaller changes for lambdas and it doesn't appear for me:

So backporting some of the changes or using the fork could be options.

I have a plugin with elm syntax, as well, but I thought that it's good to have a plugin shared across the community.
