Re: backglue.c sometimes falsely returns LDAP_SIZELIMIT_EXCEEDED (ITS#2888)

[Kurt@OpenLDAP.org]

Ralf is correct here.

A size limit exceed error (not to be confused with
administrative limit error) should only be returned when
the limit is exceeded.  If the limit is 1 and there
is only 1 entry to be returned, that limit has not been
exceeded.
