show_ouput works like check_output, but showing progress

show_output() works like check_output() (including the input= keyword parameter), but will display the progress to stdout. The total output is returned to the caller, or passed back in the Exceptions output attribute, raised if the return code from the calling process is non-zero.

If verbose argument is < 0 then no output is shown, but the result still returned
