I'm not sure this is allowed by POSIX, but at least this regresses for other
reasons of EBADF like when the file descriptor is valid but not opened for
writing:


  $ echo | /usr/bin/tee >&0 ; echo $?
  /usr/bin/tee: standard output: Bad file descriptor
  /usr/bin/tee: write error
  1

  $ echo | src/tee >&0 ; echo $?
  0

As process substitutions give not that exact control over what happens anyway,
I'm 20:80 for adding because the proposed EBADF handling is blurring the
situation for all other cases which are relying on exact error diagnostic
and exit code.

Have a nice day,
