you may have a look in output-lib.scm
You'll see I just copied and modified the code. :)

Well, I'm not a developer, but I'm sure they will agree, when I say: a
bar at the beginning of a line is nonsense.
The following illustrates a curious output, if this would be the default:
\relative c' {
c1
\break
\bar ":|:"
\once\override Score.BreakAlignment #'break-align-orders =
#(make-vector 3
'(left-edge
staff-bar
ambitus
breathing-sign
clef
key-cancellation
key-signature
time-signature
custos))
d1
}
A vertikal line at begin should be the duty of the SystemStartBar. But
because I didn't manage to hack the SystemStartBar to the desired
output, I created this workaround.
BTW, it will only work with \bar "|" . If you want e.g. \bar ":|:" at
a linebreak more hackish trickery is needed (and I'm not sure, if it
will work at all)
Best,
Harm
