:break command should recognize also nonexported top level symbols in qualified IDs
When a breakpoint is defined for a qualified function name (* (*' conid . **)+ *varid' *). Then the name should be found even when it is not exported (i.e. when varid is not in the export list).[[BR]] The qualification ensures no ambiguity can happen so it should be allowed since it is line number independent which means breakpoint definitions sourced with ":." would be more robust against code modifications.
