Did `make test` in lang/ghc with and without the patches and got the
same three failed tests in both, with no evident relation to the text
package. Further, I ran the tests in the patched `text` library and they
ran fine; had to make a minor modification for the tests to build due to
QuickCheck drift but that's of no significance. So it all looks good to
me. Phew!
