Comment:

 I've committed a fix.  Indeed this is an old one!

 Ian: this could happily go in 6.8.2 if it's not too late. At first I
 though "HEAD only" but dfranke says it's important to him.  It affects
 only the pretty-printing of `HsSyn`, which is rarely used except for
 debugging.

 (dranke: I'd be interested to know what your project is.)

 I have not added the regression test, because really we should test all of
 `HsSyn`.  But we could easily add it.

 Simon
