Nice.
Obviously this would affect the environment while am is running, and
the change is observable by post-applypatch hook. I am not sure if
this change-in-behaviour would negatively affect people's hooks, but
given the large end-user population we have, somebody somewhere will
get hit.

2-element rotating buffer because we happen to care at most two
idents at the same time, author's and committer's?
How many callers of fmt_ident() do we have these days? I wonder if
we can introduce a new API that lets/forces the caller to prepare a
strbuf and migrate the current callers of this function to it, of if
it is too large a churn for the purpose of this series.
Thanks.
