FWIW, I have been playing with the addition of a ErrorContextCallback
in tokenize_auth_file(), and this addition leads to a really nice
result.  With this method, it is possible to know the full chain of
events leading to a failure when tokenizing included files, which is
not available now in the logs when reloading the server.

We could extend it to have more verbose information by passing more
arguments to tokenize_auth_file(), still I'd like to think that just
knowing the line number and the full path to the file is more than
enough once you know the full chain of events.  0001 and 0002 ought to
be merged together, but I am keeping these separate to show how simple
the addition of the ErrorContextCallback is.
