" driver/Main.hs
  * Moved the response file handling into ResponseFile.hs,
    updating import section as appropriate.
* driver/ResponseFile.hs
  * New file. In anticipation that maybe some day this could
    be provided by another library, and to make it possible
    to unit test, this functionality is pulled out of the
    Main.hs module, and expanded to support the style/format
    of response files which gcc uses.
  * The specification for the format of response files which
    gcc generates and consumes, seems to be best derived from
    the gcc code itself (libiberty/argv.c), so that is what
    has been done here.
  * This is intended to fix haskell/haddock#379
* driver-test/Main.hs
  * New file for testing code in the driver source tree
* driver-test/ResponseFileSpec.hs
  * Tests, adapted/adopted from the same gcc code where the
    escaping/unescaping is from, in the hspec style of unit
    tests
* haddock.cabal
  * Add the driver-test test-suite.  Introduces a new library
    dependency (upon hspec) for the haddock driver target in
    the haddock.cabal file, but practically, this should not
    be a problem as the haddock-api tests already depend on
    hspec.

than spaces, since spaces may be within the parameters.
This simple approach avoids having the need for any
quoting and/or escaping (although a newline char will
not be possible in a parameter and has no escape
mechanism to allow it).
