Hi Dmitris,

Bad news. Looks like SystemStartSquare is hardcoded at 0.8 staff spaces 
(source: System_start_delimiter::line_bracket in 
system-start-delimiter.cc). It's possible to fix, but it will probably 
require Scheming.

However, my attempt at reproducing looks different from your screenshot:

\new StaffGroup \with {
  systemStartDelimiter = #'SystemStartBracket
} <<
  \new StaffGroup \with {
    systemStartDelimiter = #'SystemStartSquare
  } <<
    \new StaffGroup \with {
      systemStartDelimiter = #'SystemStartSquare
    } <<
      \new Staff { c'4 }
      \new Staff { c'4 }
    >>
    \new Staff { c'4 }
  >>
  \new Staff { c'4 }
> >

Apparently something in your code has squashed the delimiters together. 
Was that intentional? It would be helpful to see a minimal working 
example showing how to reproduce the screenshot.
