(Which is about the same as my earlier suggestion, plus the added
ETA.  I do know where Brian's got that idea from. :-)

Progress indicators don't make any sense when the output is captured,
regardless of whether it's in vi, Emacs, or just in a file.  They
only make sense when output is a tty.  So i think it's OK to turn -q
automatically on when output is not a tty.

In Emacs, you get something like:

$ avrdude -pm128 -o/tmp/foo -v

You can't have that.  So just make it work for a terminal, and provide
an option to turn it off for those who don't like it at all (e. g.
since their tty output is too slow).
