Indent

[Dimitri Sykias]

I have some musical examples separated by text. 
Each musical example is intended using a layout block with indent = #8, 
although in some examples I want an indent = #0. How can I achieve this?
Thanks for your help.

\layout {
  indent = #8
  #(layout-set-staff-size 20)
  ragged-last = ##t
}
