yes, that's the purpose of the spacer.

Thank you for this insight. I worry what else altering this value might
change, but can find no reference to break-align-symbols, a search on
lilypond.org gives just one hit for
break-align-symbol (not symbols) - namely

http://lilypond.org/doc/v2.20/Documentation/internals/doublepercentrepeat

which lead me to

http://lilypond.org/doc/v2.20/Documentation/internals/break_002dalignment_002dinterface


which still doesn't mention a property break-align-symbols ...

I'm guessing setting this must impact something else, as otherwise the
present default just leads to the rather unusual typesetting for the
trailing key change.
