Mathieu,

Great! I chose this PR because I wanted to learn when patching was deemed appropriate. Thank you for the suggestion.

Hello Stephen,

As this project seems unmaintained and the last release was in 2016, I
think the best option would be to package a 0.14.0-1 based on
helm-projectile last commit.

Thanks,

Mathieu
