Thanks for using that naming scheme. I think if we do move to allowing
config-based hooks, the config schemes will mesh together well.

There's an undocumented assumption that the caller has confirmed that
the key starts with "hook." here. Can we be a little more defensive and
do:
if (skip_prefix(key, "hook.", &key))
return 0;
here (we could even drop the check in git_default_config).
Or we could use parse_key(), which is designed for this:
if (parse_key(key, "hook", &subsection, &subsection_len, &key) < 0 ||
!subsection)
return 0;
if (!strcmp(key, "errorbehavior"))

Maybe this would be simpler to follow by using an enum for the handler
return value?
Aside from these nits, the code looked sensible to me.
