[commit: ghc] master: Bump haddock.base max_bytes_used (8df7fea)

[Simon Peyton Jones]

Ha.  max_bytes_used is vulnerable to exactly when gc strikes, so I'm disinclined to get stressed about this.  I was mis-reading it as bytes-allocated.  Interestingly it doesn't happen for me.

| Interestingly, bytes_allocated did not change a bit!
