Regression: Syntax error in -ddump-minimal-imports for records in GHC 8.0

I found a bug in GHC 8.0.1.

File:

import Data.Version

main = print (versionBranch undefined, versionTags undefined)

Run:

~/.stack/programs/x86_64-linux/ghc-8.0.1/bin/ghc --make Main.hs -ddump-minimal-imports && cat Main.imports 

import Data.Version ( Version(versionTags versionBranch) )

See how there's a comma missing after versionTags? This happens for all record functions.

It works fine in GHC 7.10.3:

~/.stack/programs/x86_64-linux/ghc-7.10.3/bin/ghc --make Main.hs -ddump-minimal-imports && cat Main.imports 

import Data.Version ( Version(versionBranch, versionTags) )
