The attached is a quick patch for fetch(1). It adds a new option (-g)
that forces the transfer progress to be printed, even if it thinks that
stderr is not a tty or that it is not the foreground process.
This is useful for me in a program that runs "make fetch" in a port
directory through a pipe and wants to keep tabs on the download
progress. Modifying fetch seemed to be the simplest and most
straightforward of all my options; rather than requiring wget or
re-implementing some of make's logic.
Hopefully this will be useful to someone in a similar situation.
