PATCH: _arguments with multiple sets

PATCH: _arguments with multiple sets

[Sven Wischnowsky]

Oliver pointed out to me that completion after `compdef -' was buggy
because the `-a' and `-n' options were listed multiple times.  That's
a result of _compdef using _arguments with multiple sets and the
C-code not removing multple identical specs reported back to the shell
code.  Here's a patch for that.
