operations.download() doesn't have all privileges

[vain]

Upstream bug report: fabric/fabric#700

For us, it means that download() is pretty useless. A lot of stuff is not readable for ordinary users.

I'm inclined to implement the sudo cat hackaround.

sudo cat does not work reliably. Fabric decides to strip trailing newlines.

Options:

1. Do a sudo cat | base64. Feels like a joke, increases size of transferred data, but produces correct results.
2. Do a t=$(mktemp); cp $file "$t", download the temporary file using fabric.get, then rm "$t". Slow and might leave data hanging around in /tmp.

I'd go for option number 1.

Aure you sure that's fabric? I smell LineBuffer.

I was originally thinking gzip instead of base64, but apprently we can't handle non-ASCII output for node.run() at all. :(

Looks like this LineBuffer thing needs a makeover.
