Actually, I ran across a case of this just recently. If you are writing
a graphical interface that wraps git, scraping "--progress" output from
a pipe is the only way you can provide a progress meter within your
interface. That is what the "GitHub for {Mac,Windows}" interfaces do
(they also use libgit2 where possible, but it is far from feature
complete).
