Back-porting pattern synonym type signature syntax for GHC 7.8.4 [Re: ANNOUNCE: GHC 7.8.4 Release Candidate 1]

[Simon Peyton Jones]

The issue is not so much timing for 7.8.4 (it's a modes change to pretty-printing only) but rather that it would make 7.8.4 behave differently to 7.8.3 (although similarly to 7.10). We typically do not do that.  And the same would be true of 7.8.5.
