Repeats starting and ending in mid-bar?

[David Kastrup]

Hi,

I'm occasionally repondering the barline |: :| issue and I want to know
if anybody's music typesetting theory text or private music library has
examples of repeats starting and/or ending in mid-bar.  I seem to
remember that there is some weakened double bar in use for that,
something like ||: :|| instead of the current .|: :|. (according to our
notation).  Do I remember right?
