ldapsearch rev 1.241 "allow continuous mode" introduced one bug and one
probably-byg:

* ldapsearch -f/dev/null returns an uninitialized value 'rc'.  Fixing.

* last instead of "worst" search return value is returned with continuous
  mode.  I.e error followed by success returns success.  I assume it should
  return failure like ldapmodify (see the code which saves rc in 'ret')?
