[PATCH] Add d[N] to download Nth link Export this patch

I wanted to add an optional [N] to 'd' and '|' to download/pipe the
Nth link instead of the current page. After getting the first one done,
I found out that '|' already has this option, so I fixed the relative
help line without changing that command.

All in all I don't know how useful this patch is, considering that
'[N]|' was already there. Feel free to discard it and just keep the
documentation change.
