Regression in parsing hscolour.cabal

[AlexandreTunstall]

After updating MicroCabal to 0.5.8.0-4568cc27378c95585617ba1ec96cbf0ab71fd688, it fails to parse hscolour.cabal.

mcabal: uncaught exception: error: "src/MicroCabal/Parse.hs",32:34: 
  found:    '\FS'
  expected: ',' '"' word
  file: "hscolour.cabal"
  line: 47
  at: "\n\n\nExecutable HsColour\n  Build-depends: base < 10, containers\n  Default-Language: Haskell98\n  Main-i"

Version 0.5.3.0-31f1b5dec81561a1b1d36b8e3065ce091dce2ec6 is able to parse the file without issue.
