ldapmodify doesn't report errors from a failed ldap_result() call. This can be
reproduce by using ldapmodify via stdin and connecting to a server with a very
short idletimeout. If the MODIFY operation is sent after the connection is
closed no error message is shown to the user. The only indication of a failure
is the EXIT code of ldapmodify.

This is fixed in HEAD now.
