We stopped doing this because scp would say things like "no such file
fs:foo/_darcs/format" when Darcs was working perfectly well, and this
was very confusing.  I guess progress bars were line-buffered or
suppressed, which is why you never saw them back then.

Note that for a modern setup, scp isn't (AFAIK) used at all.  The two
pipelines are

    darcs pull fs:foo --> ssh fs darcs transfer-mode --repo foo
    darcs push fs:foo --> ssh fs darcs apply --repo foo

So essentially you're talking about implementing progress notifications
within transfer-mode, I think.
