Let's make the commas optional. The 6.4 release candidate has already
gone out, and people are starting to build Cabal package descriptions
based on the existing syntax, so it would be unfortunate if we had to
break those.

"extra" makes sense in this context, because they are in addition to the
Haskell libraries (hs-libraries). We can do s/libs/libraries/g if you
like.

For quoted strings we use Haskell's lexical string syntax via Read/Show,
so this isn't an issue I think.
