Cabal bug, times two and a half

I tried reporting a Cabal bug via Trac, but I can't log in as guest/haskell. Alas. The bug is that "runhaskell Setup.hs --enable-library-profiling" doesn't imply -auto-all with ghc, so the profiled library contains only manual cost centres - in other words, it never shows up in profile output. The second bug is that the only way I can find to override or add compiler flags is to edit a .cabal file by hand. This makes it scarily easy to capture unintended flags when committing changes :-(
