I found it here. http://wiki.tcl.tk/1632. It hints that it may not be unoffical. Seems to
original from: http://groups.google.com/group/comp.lang.perl.tk/browse_thread/thread/5b6f4c6a4a9f17b4...

so if someone thinks there is a problem we could replace it with UnderlineAmpersand
with tcl code to do the same (or rip it as is if the license allows it).

In theory we should translate && to & also, which UnderLineAmpersand does.
