REVISION SUMMARY
  When /home is a symlink, for instance (as is often the case on FreeBSD),
  group deletion would fail because KConfig was comparing non-canonical
  paths with canonical-paths:
  
  QDEBUG : KConfigTest::testDelete() Comparing "/home/adridg/.qttest/config/
  kconfigtest_subdir/kconfigtest" and "/usr/home/adridg/.qttest/config/
  kconfigtest_subdir/kconfigtest"

TEST PLAN
  mkdir /tmp/derp; ln -s /tmp/derp /tmp/drop
  HOME=/tmp/derp bin/kconfigtest testDelete  # Success
  HOME=/tmp/drop bin/kconfigtest testDelete  # Fail

REPOSITORY
  R237 KConfig

BRANCH
  master
