Progress bar: Visual Bug
There is a visual bug in the progress bar that can be recreated using the following commands:
$ clear
$ wget2 --progress bar example.com
You will see that the first line of the console gets scrolled up as a result of the command. This should not happen. However, we don't see any weird behaviour when wget2 is not the first command executed on a clean terminal. This implies that the bug is caused due to excessive cursor movements.
