Title: Don't export 'i' and 'cmd_output' as global vars

Hi - I ran into a problem when trying to run something along the lines of `for i in foo bar; do echo $i; done`, which doesn't work as expected when 'i' has previously been exported from one of scm_breeze's for loops. This patch ought to fix that, as well as cleaning up the only other global I could find (cmd_output).
