> commit 2a2f5530fa230e2b994be5683e63763833bb6a0a breaks
> ldap-search-internal for searches with empty results.
> 
> Consider this search with ldapsearch, returning an empty result:
> 
> ldapsearch -h ldap.pca.dfn.de -tt -x -b O=DFN-Verein,C=DE \
> '(mail=x <at> example.org)' userCertificate
> # extended LDIF
> #
> # LDAPv3
> # base <O=DFN-Verein,C=DE> with scope subtree
> # filter: (mail=x <at> example.org)
> # requesting: userCertificate 
> #
> 
> # search result
> search: 2
> result: 0 Success
> 
> # numResponses: 1
> 
> The problem is that ldap-search-internal interprets the 2 in line
> "search: 2" as filename with a certificate, bound to variable value.
> Thus, (insert-file-contents-literally value) results in an error:
> File is missing: "Opening input file", "Datei oder Verzeichnis nicht
> gefunden", "[currentdir]/2"
> 
> Execute that:
> (let ((ldap-default-base "O=DFN-Verein,C=DE")
>       (ldap-ldapsearch-args '("-x" "-tt" "-H ldaps://ldap.pca.dfn.de"))
>       (search-plist '(host "" filter "mail=x <at> example.org" attributes ("userCertificate") attrsonly nil withdn nil)))
>   (ldap-search-internal search-plist))
> 
> Previously, that returned nil, after the mentioned commit it
> produces the above error.

> The added “?” should be removed there again:
