My understanding is that > dash's new behaviour (and incidentally, ksh93's one) is incorrect. Is your question about POSIX or about correct behavior in Debian? If POSIX, the list to contact is austin-grou...@opengroup.org. If Debian, please feel free to brainstorm at debian-devel@, to provide supporting information to d...@packages.debian.org (or any dash bug report), to clarify policy using the debian-policy@ list, or to consult debian-ctte@ if you do not trust Gerrit's judgement.
