Details:

Hello,

an old forgotten bug report:

--8<--
When wget is suspended in command line and then
send into background (eg using bash bg command), it continues
to print it's progress messages. This leads to either stopping
wget or to garbling terminal with wget messages (depending
on the TOSTOP terminal setting).
--8<--
My suggestion is to stop printing verbose progress messages
when the job is resumed in background. It could be checked
by (successful) getpgrp() not equal to (successful) tcgetprp(1)
in SIGCONT signal handler.
 And something like this is used in some console applications,
for example, in lftp.

As an example:

# wget
http://cdimage.debian.org/debian-cd/current/multi-arch/iso-cd/debian-8.1.0-amd64-i386-netinst.iso
<Press ctrl+z>
[1]+  Stopped              wget
http://cdimage.debian.org/debian-cd/current/multi-arch/iso-cd/debian-8.1.0-amd64-i386-netinst.iso
address@hidden:/tmp/test$ bg
<garbling the terminal but commands work as expected>

Regards

Noël
