Title:
  add-apt-repository won't uncomment a commented-out source

Status in “software-properties” package in Ubuntu:
  Triaged

Bug description:
  Assume you're frequently testing software, so you add, remove (purge)
  and re-add PPAs.

  sudo add-apt-repository lp:someteam/ppa
  sudo apt-get uppdate
  sudo apt-get install someprogram

  ... time passes and you no longer need that program, or wish to test
  your system without it ..

  sudo ppa-purge lp:someteam/ppa

  This will remove the ppa by commenting out the "deb ..." line in the
  sources file in /etc/apt/sources.list.d

  Later, you need to do more testing of the app or some other app from
  the same ppa so you re-add it:-

  sudo add-apt-repository lp:someteam/ppa

  However, this does _not_ add the PPA because the line/file already
  exists, albeit with a # in front of the "deb ...".

  Some might argue that it is the fault of ppa-purge for commenting the
  line out. I disagree. I believe ppa-purge _should_ comment out the
  "deb ..." line because sometimes you want to go back to the file to
  remind yourself what the ppa was that you got something from, or to
  just manually re-enable it.

  Given the single role of add-apt-repository is to add a ppa, I'd
  conclude it's add-apt-repository which is broken, given it doesn't add
  one in this common scenario.
