push/fetch/clone --no-progress suppresses progress output

By default, progress output is disabled if stderr is not a terminal.
The --progress option can be used to force progress output anyways.
Conversely, --no-progress does not force progress output. In particular,
if stderr is a terminal, progress output is enabled.

This is unintuitive. Change --no-progress to force output off.
