A few small fixes to make things like image list not
print "//mach_kernel" if you are debugging an executable
in the top level directory.
Don't break comments after includes.

LLVM/Clang basically don't use such comments and for Google-style,
include-lines are explicitly exempt from the column limit. Also, for
most cases, where the column limit is violated, the "better" solution
would be to move the comment to before the include, which clang-format
cannot do (yet).
