On some (probably buggy) terminals, printing up to the rightmost column
may end up with the terminal issueing a newline (probably due to putting
the cursor at the next char -> new line).

Some other progress bars avoid it by not reaching the rightmost column.

Shorten the bar width from term-width - 7 to -8 (the 7 are "xxx% []").
