What you may have there is the shell $( ) handling changing the
program's output. Try piping the command into 'hd' or similar to see
what it actually produces; it's entirely possible the \n is there, and
the shell is stripping it.
In any case, you can easily trim whitespace from inside Python. That
would be your workaround, I think.
