[gabrtv]

Replaces #59.

[gabrtv]

Note we still need to cleanup extraneous mc output from slugbuilder.

Closes #58

[arschles]

@gabrtv this looks to effectively stream logs from slugbuilder, but it still shows mc output (see below). I think the problem is that both stdout and stderr are streamed across the SSH conn at https://github.com/deis/builder/blob/master/pkg/git/git.go#L162-L163. Thoughts on piping mc output to /dev/null for now?

@arschles hmm i'm not seeing all of that output, but I agree we can shift output to /dev/null for now. I know a lot of that output is from slugbuilder. One sec..

[gabrtv]

Shifted some stuff to /dev/null. Here is the new output. I'm almost positive the mc debug you see is coming from slugbuilder:
