I never used 'git submodule clone' but with 'git clone' these lines seem to overwrite one after another and they never bothered me. Could your terminal emulator be broken?

... thinking about it, it's obvious why Capistrano doesn't handle the
\r properly - it's running commands in parallel on multiple machines,
and echoing any output from the commands (prefixed with the machine
name) back to the user in realtime.  So it would be kinda tricky for
\r to work as expected there.
