For context, all changes in the paper are to [lex.ccon].

In paragraph 2, the following additional change would be appropriate (since
there is only one applicable base kind now):

their respective base kinds => the base kind

For the change to bullet 3.2.2, the discussion in the paper does not
propose a change to the status quo regarding numeric escapes. The proposed
change to this bullet should be omitted. That is, L'\x80000000' remains
valid when wchar_t has a signed 32-bit underlying type.

The rest of the changes appear sufficient and in line with my understanding
of the consensus out of SG16.
