That’s not enough: #'("|" "|" "|") will make full bar lines at line 
breaks. When I try #'("" "" "|") instead, no span bar is printed at line 
end. But the following seems to work:

%%%%%

\version "2.21.0"

\defineBarLine "-m" #'("-m" "" "|")

\layout {
  \context {
    \Score
    defaultBarType = "-m"
  }
}

mus = \relative {
  \repeat unfold 12 { c' d e d } \bar "|."
}

\new StaffGroup <<
  \new Staff \mus
  \new Staff \mus
>>

%%%%%

I’ll try to explain what I think is happening here:

• in the middle of a line, the staff bar is taken from the name "-m" and 
the span bar from the third argument "|"
• at the begin of a line, the second argument is used: "" is an empty 
staff bar *with empty span bar* (default for "" bar lines)
• at the end of a line, the first argument is used: "" is not sufficient 
here, because the span bar is taken from the "" definition instead of 
the third argument; setting the first argument to "-m" looks into the 
third argument of this definition.
