A .cabal directory is incorrectly considered a project indicator #1391
Description
When using cabal, a .cabal directory will exist inside the user's
home directory. Currently, projectile will interpret that as
a Cabal project existing directly in the home directory, and thus
every file opened that does not belong to a more specific project will
be categorized as a Haskell Cabal project.
Steps to reproduce the problem
Create a .cabal directory in your $HOME, the open a file in any directory that does not belong to a projectile project. Your buffer will be incorrectly be classified as belonging to a cabal project.
