[optional.syn] const placed on right

[sdutoit]

Alisdair says:

// 20.6.4.5, observers
Pointers and references are placing 'const' on the right,
but standard is fairly consistently 'const' on the left.
(even though I prefer on-the-right myself!)

I started by fixing this for pointers throughout the draft in ce29631 - references are next, and the fixes won't be limited to just this section.

Err; technically the last comment was only related to this and not exactly the same, but it's in the same ballpark.

Is there any chance we get const to the right?

What is the state of this issue? I found the inconsistency still exists widely even in same subclause, e.g. mutex(const mutex&) = delete; vs. lock_guard(lock_guard const&) = delete;.
