I think somewhere in the discussion leading to this patch was a rational
why wcwidth is special here, I already can't remember. Maybe it would be
worth it to add that rational to the commit message.

AFAIU all the wc-funcs are now part of ISO C or POSIX and systems not
supporting it are legacy. Deprecating is fine, maybe don't put 2.5.0 as
a hard deadline (just in case). If someone somewhere is really building
a modern mutt on such a legacy system they can come to the ML and
complain.

With my above comment about the rational in mind:
OK [or Acked-by: ;)].
