Yea -- I built a machine and tried it.  I got the same result.  The '> *'
looks like it should truncate all files.  '> filename.ext' truncates the 
named file, due to a quirk of redirection.  I think if '*' were to 
evaluate to a single filename, that would occur.  If you do this:

	> first.ext second.ext third.ext fourth.ext etcetera.ext

then the shell should try to truncate 'first.ext', then execute 
'second.ext' with 'third.ext fourth.ext etcetera.ext' as arguments and 
redirect STDOUT to 'first.ext'.

I'm not sure why '*' evaluated to a list of files, doesn't bring about the 
same result.
