brew cask list in a dir containing installed cask file(s) results in file does not exist error

[IshmaelYavitz]

I try to use homebrew-cask to install all software. So I create cask files locally.

If I do a brew cask list from a directory containing one of those files, and the cask is still installed, it fails. If do it from a directory that doesn't contain any cask files for installed programs, it succeeds.

In the failure case, brew cask appears to be looking for a file with the correct name but without the .rb extension.

Demo:

(I doctored the successful output of brew cask list to put individual casks on their on line.)

Closing as I’ll link to it in a single issue pointing out brew cask list bugs.
