git tree commit hook requires something of the form "Name Surname"
in the signed-off lines. Can you use a name of this format?

I propose the attached patch. Please test that it works on clang 9.

I assume we will need to massage every SET_PTR_TO_GLOBALS(xzalloc(sz))
to something like XZALLOC_PTR_TO_GLOBALS(sz) too?
The bug may be occurring there as well, right?
