I have a pre-release make target where I test everything I can think of. 
  I think it prevents the above, am I right ?

  # run pre-release checks: cabal is happy, the code builds, tests 
pass..
  check: setversion unittest doctest haddocktest 

    cabal clean 

    cabal check 

    cabal configure 

    cabal build 

    dist/build/hledger/hledger test 2>&1 | tail -1 | grep -q 'Errors: 0 
  Failures: 0'                                                   |
