Ah, well in that case I should give the correct version;  sed above will
be putting out what was originally stderr on its stdout, which is pick's
stdout.  It's better with a `>&2'.

    $ ls -d / /known /unknown 2> >(sed '\#/known:#d' >&2) | sed 's/^/1:/'
    ls: cannot access /unknown: No such file or directory

Cheers, Ralph.
