#2159 PR 778511 needs to be reopened:Elide text scrolling doesn't

[Russell Owen]

PR 778511 (which has been closed) is still a problem. I see it in two
cases:
- MacOS X 10.4.7 running Aqua Tcl/Tk 8.4.13.
- Linux running Tcl/Tk 8.4.7

PR 778511 include a demo script that works well (once you translate
the html entities). I will attach a translated version to speed up testing.
