ls output is unfriendly if any element in return contents is longer than terminal width

When 'ls' operation is performed over 'provider-loader' element, the output is very ugly - I get many empty lines with one very long attribute value and few more attributes with simple values.

Expected: no empty lines between printed attributes so the output does not take like 4 screen size.

Steps to reproduce:

1. prepare WF based on wf-core
2. start WF
3. ls /subsystem=elytron/provider-loader=elytron
4. see very long output with many empty lines between particular attribute records printed
