 An ASSERT macro in compiler/coreSyn/CoreSubst.lhs isn't being expanded
 because of a space before the parens. The error:

 /usr/local/bin/ghc is version 7.6.3. I'm building HEAD, which is at commit
 5d04603b33d285565774, though a27b2985511800fa3b740fef82 (HEAD~2)
 introduced the code in question.

 This is, I'm pretty sure, literally a one character (and a whitespace, at
 that) fix. Attached is the patch.
