This affects an invokation using the shell's background operator (&) too.
E.g.: wget http://cdimage.debian.org/debian-cd/current/multi-arch/iso-cd/debian-8.1.0-amd64-i386-netinst.iso & will cause the logging output and progress bar to be displayed on the terminal as explained in the bug report. However, I am not willing to fix that behaviour. A huge number of people copy URLs and paste them in their terminals for Wget to download without double-quoting them. A large number of these URLs have the "&" character which causes the shell to background the process. They tend to realise that something went wrong when the screen is garbled by a background process spewing messages to stdout and stderr. If this behaviour is changed, many people won't realise their error and un-necessarily invoke multiple instances of backgrounded Wget processes, eventually coming back here with new bug reports. The bahviour has remained so for a long time and I'm inclined to retain the status quo.
