I should have tried to explain this in my earlier message...
The original code is very clear, the new code works exactly the same but
it's not clear if the author forgot about handling errors from
audit_log_start(). So now someone will come along later and add:
if (!ab)
return;
We get a lot of mindless "add error handling" patches like that. Even
if no one adds that patch who ever is reading the code will think that
the error handling is missing by mistake and have to read the git log
to determine the original intention.
Instead of hiding the readable code in the git log, let's just leave it
in the source file.
