This works fine on 6.3 in a custom window, channel window and status window.
There may be a discrepancy between $line() and the window buffer size because wrapped lines are counted differently in these routines. Also, since lines are wrapped on-the-fly ie. only when they are actually visible, there may be a further discrepancy. The window buffer size is mainly used to limit memory usage for users who need it, so it's really a round-about number, not a precise line count.
