LC Syntax WD changes (was Re: Syntax: positive review)

I'm replying to this mail (again) in order to note:
   what I'm doing now for LC WD (critical fixes, minor stuff) - "Done"
   versus after LC - "Later"
   or not doing - only one of these, it was a spelling.

As I already replied, the "Later"s are mostly likely to be accepted
after some further consideration and possible some more rewording,
after last call.

I'll be uploading the changes to the LC WD area later.

It seems so.  Not changing.

I don't see this problem in that para.  I couldn't find it elsewhere either.

Fixed by the 5.1 change I think.  Look at later too.
