How do I get rehearsal marks at both end and beginning of lines?

[Robert Kennedy]

I want a rehearsal mark at the end of one line, and a different
rehearsal mark at the beginning of the next line.

It seems to be a bug that rehearsal marks are junked as duplicates
without regard to different values of their break-visibility
properties.

One of the rehearsal marks in the following files disappears. How do I
get them both to appear in the right places?

             \mark \markup { "end of line" }
             \break
             \mark \markup { "beginning of line" } d'' }
