The problem is that the lexer just gives us `${(k)opt<TAB> | grep glob'
as the string to complete. Then the completion code parses this and
takes `opt | grep glob' as the parameter name.
A simple fix would simply remove that part of such a string that can't 
be used as a parameter name. However, this would also mean that the
rest is completely ignored and does not even show up in $words.
The patch below does this, because trying to solve it in a way that
preserves the information about following words would be pretty
complicated (either temporarily inserting a closing brace when calling 
the lexer, but first finding out when this has to be done, or fiddling 
with the lexer, which is completely unacceptable).

Ok?
