Figure out a better way to do this

[eqyiel]

This works:

(apply 'call-process
 prettier-js-command nil (list (list :file outputfile) errorfile)
 nil (append (append prettier-js-args width-args (list "--eslint-config-path" "/Users/rkm/git/mango-chutney/steptember/.eslintrc.json")) (list bufferfile)))

But it's not nice to use if we have to specify the path every time.

It looks like prettier-eslint tries to find the eslint config file itself if you give it the filePath prop.
