It seems that "cherry-pick A..B" leads to sequencer.c::run_git_commit()
that uses run_command_v_opt() to drive "git commit", so we are safe.

ident_default_date() is currently the only one that sets this to be
cached, and that is to be used only when there is no user-specified
date.

When I saw the suggestion first time, I was worried if this had
interaction with things like GIT_COMMITTER_DATE environment (because
I didn't have easy access to the source) but it is not the case, so
the change looks very sensible.
