Hm, are you using my jigdo-lite or Anne Bezemer's version (from
cdimage/~costar)? My version is much simpler and not screen-oriented,
so it doesn't overwrite any old screen content.

What does happen, though, is that a lot of text is output as time goes
by, so if you do not configure your terminal to buffer several
thousand lines of output, old text will eventually disappear.

That's difficult to achieve because the output

  0K .......... .......... .......... .......... .......... 26% @ 980.39 KB/s

is created by wget, not by jigdo-lite. For the next release, I'll pass
the --dot-style=mega switch to wget, which will reduce the amount of
dots that are output.

Hm, I just noticed I could do 
  wget ... 2>&1 | tr '\n' '\r'
but then any wget error messages would never be visible on screen,
which is not desirable.

There actually *is* a (admittedly /very/) crude progress report: At
regular intervals, jigdo-file is invoked by the script and prints
something like:

  Found 10 of the 1423 files required by the template

The second number decreases as time goes by - when it reaches 0, the
download is finished.

Thanks for your feedback!
