Copy-and-pasted, but if you want to tweak the grammar to all of the
patches with identical bodies:
If we want to append a hint to errp, we must use the ERRP_FUNCTION_BEGIN
macro. Otherwise, the hint will not be appended when errp == &fatal_err
(the program will exit prior to the error_append_hint() call). Fix such
cases.

Should the commit-per-subsystem.py script append a distinct CC: line as
long as it is already grouping files by maintainer?

It's probably easier to take this entire series through one maintainer
(Markus, since it is error-related), than to have me pick up this patch
by itself through the NBD tree.
