log message changes (warning: minor backward compat breakage)

The log message format has changed.  All log messages now have a common
prefix (timestamp, user, IP).  This is followed by $SSH_ORIGINAL_COMMAND
(or, in one special case, the name of the user's login shell).  Any
further text appears after this (currently this only happens in the case
of a successful push -- one for each ref pushed successfully)
