I'm afraid I forgot to include this change for the CD and the next WD
(N4917), which now only has the __cpp_lib_format macro, without the
splitting discussed above. However, I believe the feature test macros are
overall editorial in nature, so I would be happy to make the change
immediately now, and nobody needs to file NB comments about it? I gather
also that there's been new discussion, so could you kindly confirm whether
the plan from my previous mail is still acceptable or whether we'd like a
different set of macros now?

All the best,

Thomas
