I haven't been following the thread, but is this what you are talking
about?

    Ordinarily, functions that operate on text or move point do not care
    whether the text is invisible.  The user-level line motion commands
    explicitly ignore invisible newlines if `line-move-ignore-invisible'
    is non-`nil' (the default), but only because they are explicitly
    programmed to do so.

    However, if a command ends with point inside or immediately before
    invisible text, the main editing loop moves point further forward or
    further backward (in the same direction that the command already
    moved it) until that condition is no longer true.
