I don't know much about the internals of completion, but I like where
this is heading.

This change looks good overall, but I have a few nits, though.

Both branches of the if-else statement start with the same

	    local cur
	    _get_comp_words_by_ref -n =: cur

so these could be moved out in front of the if statement.

The 'sync,*' case is not necessary, because it has the same completion
reply as the '*' case, and that case would match it anyway.

And finally, please use tabs for indentation.
