Hi,

I found that ob-shell’s org-babel-variable-assignments:bash function does not respect the interface for org-babel. It takes multiple arguments when it should only take 1. This is a problem when f.ex. org-babel-sha1-hash tries to expand the body of a bash source block and tries to call that function with only 1 argument.

I am not sure if the following patch follows best practices in the project, but it solves the problem for me.
