[PATCH] Use ZSH_NAME instead of ZSH_VERSION because it's redefined by git-completion.zsh

[Rick van Hattem <wolph@xxxxxx>]

The `git-completion.zsh` unsets the `$ZSH_VERSION` which makes this check moot. The result (at least for me) is that zsh segfaults because of all the variables it's unsetting.
