What matters here is the mistake fixed in the manual. n>&p has
been around since the end of the 70s. It's unlikely anyone will
learn anything about it from the dash man page.=20

Let's make it:

  [n1]>&n2    Copy file descriptor n2 as stdout (or fd n1)
  [n1]<&n2    Copy file descriptor n2 as stdin (or fd n1)

That's more or less the POSIX wording. It may not be as
descriptive as other ones, but I can't imagine anyone
complaining about the correctness or accuracy of it.
