Normally, COLUMNS is set by the shell when Mercurial is invoked, and never changed during its execution. If I make my terminal window smaller, any new messages will be wrapped…

Sure, but I don't really see how it relates to the discussion: COLUMNS already overrides posix termwidth() so windows must honor it the same way. AFAIK, COLUMNS is not a default environment variable in cmd.exe, that's something you set explicitely. I see COLUMNS as a convenient option for tests or scripting, like HGPLAIN, but perhaps that's different on unix? (http://www.opengroup.org/onlinepubs/000095399/basedefs/xbd_chap08.html seems to agree with me).
