add-change-add-log-entry regression, with fix

[Roland McGrath <roland@frob.com>]

Before version 22, a function on change-log-mode-hook could set
add-log-mailing-address or add-log-full-name as a buffer-local variable in
the change-log-mode buffer and have this affect what
add-change-add-log-entry inserted in the buffer.  In 22, this is broken.

This patch restores the behavior that hooks have been able to rely on since 18.


Thanks,
Roland
