Actually this is the expected behaviour.  Any long command line option 
can be abbreviated to a shorter version, provided that it is 
unambiguous.  So for example "as --vers" will do the same thing as "as 
--version", but "as --ver" will be rejected because it could be 
shorthand for either "as --version" or "as --verbose".
