- git archive is not working like it should
- pipe to gzip for gzip compression
- Like what I have specified in the comments on lib/capistrano/tasks/gitcopy.rake
- Gave a vivid description of what I have found and the solutions to it
If the :branch cannot be found, no archive should be attempted, the file will not exist, and the task should fail.
