My understanding is that for msiexec the curly brackets are only used to 
enclose cases where there is two or more alternatives: {a|b|c}. With 
{required parameter} being an exception to the rule, maybe because it in 
fact represents a list.

It would be nice if all of Wine's tools used the same conventions for 
the usage messages.
