Git town completions for zsh not working on OSX.

[gstamp]

If I follow the docs I get an error in OSX:

❯ git-town completions zsh | source
source: not enough arguments

If I write the output of the completions to a file and source that file I no longer have the error but the completions fail to work.

Thanks for reporting this. Currently we use the built-in completion support provided by our CLI framework. These completions seem too limited for the way Git Town is used. We plan on improving the completions in #2118.

Seems to be the same on windows (had to source <(git-town completions zsh) but no completions anyways)
