Indeed.

Yes.

It is visible. What the shell doesn't like is the "@" sign (i.e., in 
"@true"). Just running "true" as Waldek suggests works fine - but the 
command line is printed (which is quite fine IMHO).  Removing the 
semi-colon and the "true" or "@true" after it also works okay - but who 
knows whether it can cause problems on another platform? So I guess we 
should simply removing the "@" sign as suggested by Waldek. I don't 
pretend to understand unix shells very intimately, so perhaps the best 
option is minimal intervention.
