Fixup no-progress for fetch & clone

dscho · Junio C Hamano · commit b0e908977ebe · 2007-02-24T00:26:18.000-08:00
The intent of the commit 'fetch &amp; clone: do not output progress when
not on a tty' was to make fetching and cloning less chatty when
output was not redirected (such as in a cron job).

However, there was a serious thinko in that commit. It assumed that
the client _and_ the server got this update at the same time. But
this is obviously not the case, and therefore upload-pack died on
seeing the option "--no-progress".

This patch fixes that issue by making it a protocol option. So, until
your server is updated, you still see the progress, but once the
server has this patch, it will be quiet.

A minor issue was also fixed: when cloning, the checkout did not
heed no_progress.
