2.8.0 doesn't make any commits

With version `2.8.0` I can no longer make any commits, where it usually prints the new commit, it doesn't print anything at all. No commit is created, no error message is printed, and the exit code is still `0`.

This is on OS X with zsh.

Reverting to 2.7.8 fixes the problem

Reproduzca el commit command en OS X con zsh usando cz-cli 2.8.0 y compare su comportamiento con el de 2.7.8. Trace por qué 2.8.0 termina correctamente sin crear ni informar de un commit, y verifique que el comportamiento corregido cree el commit e imprima el nuevo commit.
