Many (less easily automatically converted) old-style strings
remain.
Where there was any possible ambiguity about the exact version or
variant intended, nothing was changed. IANAL, nor a search robot.
Use `with stdenv.lib` wherever it makes sense.
Once nixpart 1.0 is released we then only need to delete one single
directory rather than searching for needles in a haystack, that is, all
of <nixpkgs>. Also, it keeps my sanity at an almost healthy level.
