Noexternalinterlang didn't work for a while as a parser function, now it works but in some cases it behaves eratically. Examples:

{{noexternalinterlang:zh|af}} - removes zh but not af
{{noexternalinterlang:af|zh}} - removes both af and zh (this is correct behavior)
{{noexternalinterlang:ar|zh}} - removes ar but not zh
{{noexternalinterlang:zh|ar}} - removes both zh and ar (this is correct behavior)
{{noexternalinterlang:ar}} {{noexternalinterlang:zh}} - removes ar but not zh
{{noexternalinterlang:zh}} {{noexternalinterlang:ar}} - removes both zh and ar (this is correct behavior)
