apt-add-repository --remove doesn't remove as expected

When running 'apt-add-repository --remove <REPO>', the deb-src repository isn't removed along with the deb repo. Along the same lines, the message when running with the --remove option is confusing (it says it is adding a repository). This may be working as designed, but it doesn't make sense as to what someone would expect to happen.

For instance, If I run 'apt-add-repository --remove ppa:alexandr-surkov/dharma-pvr', I get a new file (/etc/apt/sources.list.d/alexandr-surkov-dharma-pvr-oneiric.list) containing

deb http://ppa.launchpad.net/alexandr-surkov/dharma-pvr/ubuntu oneiric main
deb-src http://ppa.launchpad.net/alexandr-surkov/dharma-pvr/ubuntu oneiric main

If I then run 'apt-add-repository --remove ppa:alexandr-surkov/dharma-pvr', it says it is adding a repository, and the file (/etc/apt/sources.list.d/alexandr-surkov-dharma-pvr-oneiric.list) then contains

deb-src http://ppa.launchpad.net/alexandr-surkov/dharma-pvr/ubuntu oneiric main

I would expect it to remove both repositories (deb and deb-src) when running it with the --remove command since it added both when running it regularly
