Bug#852212: installing and then purging sometimes leaves behind cruft

[積丹尼 Dan Jacobson]

Package: aptitude
Version: 0.8.4-1

# aptitude install tlp
also installs hdparm,
but then
# aptitude purge tlp
does not remove it.
It does remove the rest though, thankfully.

The following NEW packages will be installed:
  hdparm{a} (D: tlp, R: pm-utils) (tlp D: hdparm)  iw{a} (D: tlp) (tlp D: iw)
  libnl-3-200{a} (D: iw, D: libnl-genl-3-200) (tlp D: iw D: libnl-3-200)  
libnl-genl-3-200{a} (D: iw) (tlp D: iw D: libnl-genl-3-200)
