delta-reduced input (not valid code but manages to make clang++ crash)

The following happens when colour_pretty_printer.cc is compiled with `clang++
-std=c++0x` and headers from libc++:

clang: SemaInit.cpp:3951: ExprResult
clang::InitializationSequence::Perform(clang::Sema &, const
clang::InitializedEntity &, const clang::InitializationKind &, MultiExprArg,
clang::QualType *): Assertion `Kind.getKind() == InitializationKind::IK_Copy ||
Kind.isExplicitCast()' failed.

As a result of running multidelta, the attached file is not valid C++ code.

This is with clang version 3.0 git-1fba8281b9fab5bf11c4083e88f31047413f94f2.
