Comment 0 for bug 1071265

Sometimes the yaml output doesn't display as literal strings the output from commands like in the following fragment:

  stderr: "DEBUG: Calling 'ls /tmp/tmpLsm5FK'\nDEBUG: stdout: file1\nfile2\nfile3\n\
    \nDEBUG: stderr: \nDEBUG: returncode: 0\nDEBUG: Checking for 'file1' in 'ls' output\n\
    DEBUG: Checking for 'file2' in 'ls' output\nDEBUG: Checking for 'file3' in 'ls'\
    \ output\nDEBUG: Calling 'ls -l /tmp/tmpLsm5FK/file1'\nDEBUG: stdout: -r-xr-xr-x\
    \ 1 root root 0 Oct 25 13:01 /tmp/tmpLsm5FK/file1\n\nDEBUG: stderr: \nDEBUG: returncode:\
    \ 0\nDEBUG: Calling 'ls -l /tmp/tmpLsm5FK/file2'\nDEBUG: stdout: -rw-rw-rw- 1\
    \ root root 0 Oct 25 13:01 /tmp/tmpLsm5FK/file2\n\nDEBUG: stderr: \nDEBUG: returncode:\
