I suppose I should've seen that in some other patch in the previous
series, but can we perhaps find a way to not have to do string
manipulation here? host.execute() should probably take a list just like
subprocess.Popen() does, and execute it as such, rather than passing it
through a shell? And even if that's absolutely not possible (using
ssh?) then we should probably do string quoting in a central place in
the code.
