Looking at the code I discover that there is already provision covering
spaces etc., because you can quote names. It's even documented ;-)

The minimal disturbance change might be to teach the parser to
distinguish between a quoted 'all' and an unquoted 'all', and forget the
'*' idea. Alternatively, do the same sort of thing, but replacing 'all'
with '*'. A patch for the first would be quite tiny - similar for '*'
except for extra doc and sample file changes.
