Hi Team,

I have a bug in the code that is simple to fix but hard to find out. It 
took me almost 30 minutes to see but it is due to the fact that yml 
indentation syntax quirkness!

Lets see the block below

- block:
    - name: disable sssd service for non production nodes by all means
      service: name=sssd state=stopped enabled=no
      ignore_errors: True
    - shell: "chmod -x /init.d/sssd.sh || true"
    - shell: "kill `ps -ef|grep '/usr/sbin/sssd' | grep -v grep | awk 
'{print $2}'` || true"
    - name: remove the sss service from nsswitch.conf
      replace: dest=/etc/nsswitch.conf regexp='^(.*) sss$' replace='\1' 
backup=yes
  when: host_type not in [ 'production', 'livepreview' ]

You see the fact that after the - it *must* be a space (right?) so the when 
condition allied to the whole block needs to be match with exactly the b of 
the block. Or course if I set tab width to 2 it would be it if the start of 
the line press tab, but if I set tab to any other size, it wont, I need to 
align it exactly two spaces!

After a long block the alignment does not look good anymore and harder to 
spot out indentation error.

Can I do something like -[TAB]block and from that only use TAB so it does 
not matter TAB size, I can always use tab for indentation?
