Why does SHM think I'm using stack?

[ivan-m]

So SHM suddenly decides that things like shm-supported-languages is not going to work because it thinks I'm using stack for a project when there isn't even a stack.yaml file in this project.

It seems that the reason being is that shm-stack-find-file is finding my ~/.stylish-haskell.yaml for some strange reason and thinking that because of that I have a stack.yaml file and thus want to use stack.

(Not to mention the seemingly redundant double-usage of not: https://github.com/chrisdone/structured-haskell-mode/blob/master/elisp/shm-stack.el#L27 )

Maybe something like what haskell-mode has could be used:

(and (locate-dominating-file default-directory "stack.yaml")
             (executable-find "stack"))

This is still happening, and causing problems when using a newer system GHC than the one used by stack.
