After the patch, in bzrlib/transport/ssh.py there should be a place
where it is calling:
subprocess.Popen(args,
		 ....)

Just add a line like:

mutter('spawning command: %s', args)

just before that.

It might also be that we need to supply something like 'shell=True', or
some other change to how we are spawning the subprocess.
