1.9.1 leaks unprefixed symbols

[agx]

These new symbols are public in 1.9.1 but not 1.9.0

 destroySchemeDetails@Base 1.9.1
 destroySchemeDetailsArray@Base 1.9.1
 destroySuggestions@Base 1.9.1
 destroySuggestionsArray@Base 1.9.1
 destroySymbol@Base 1.9.1
 destroySymbolArray@Base 1.9.1
 destroyTransliterationResult@Base 1.9.1
 makeSymbol@Base 1.9.1

I would expect these to be in the varnam_ namespace to not clash with other libraries in programs. Is the export of unprefixed symbols intentional?
