OK. I wouldn't want to use this myself, but I think you've made clear
why you find it useful. So I don't mind making it an optional behavior
(and it probably beats you trying to poke at the logfile yourself).
I'm not sure if the config is going to actually help that much, though.
The callers within Git will generally ignore the exit code anyway. So
for those cases, setting it will at best do nothing, and at worst it may
confuse the few stragglers (e.g., the git-svn one under recent
discussion).
Callers who _are_ prepared to act on the exit code probably ought to
just use --auto-exit-code in their invocation.
That said, I'm not entirely opposed to the matching config. There's
enough history here that somebody might want a sledgehammer setting to
go back to the old behavior.
