--massive-debug option produces very little debug messaging

[Jeff Lane ]

According to --help:

  -m, --massive-debug Print a lot of debug information to the command line

Now, perhaps my understanding of the words "massive" and "debug" are flawed, but the output I get while trying to debug failure to add a PPA is neither massive, nor really debug level information:

ubuntu@hogplum:~$ sudo add-apt-repository -m ppa:checkbox-dev/testing
Cannot add PPA: 'ppa:~checkbox-dev/ubuntu/testing'.
ERROR: '~checkbox-dev' user or team does not exist.

The PPA most certainly exists:
https://code.launchpad.net/~checkbox-dev/+archive/ubuntu/testing

This message is the utterly useless messaging one gets when add-apt-repository cannot talk to something upstream, be it ppa.launchpad.net or keyserver.ubuntu.com, perhaps.

Either way, "user or team does not exist" is factually wrong, and utterly unhelpful, and the level of messaging is in no way debug level messaging, nor is it massive.

add-apt-repository should actually provide MASSIVE debug level logging when -m/--massive-debug is passed to it, explaining each and every action it takes from beginning to end.
